10 panel LEDs by turning them red and then green; and it checks that the card s firmware checksum is correct If the self-test passes, the ON LED is turned green; if the test fails, it remains red The status is also reported in the Status column of the Manager s Monitor, Diagnostic, and Configuration Slot Selection screens Since a channel card cannot access the backplane unless configured by the Platform Card, the power-on self-test does not check the data path through the card If you are installing a new card in a system, perform a complete self-test on the card by going to the Manager s Diagnostics screen for that card and selecting Card Selftest The Platform Card then configures the card with a test configuration, performs a ToNet loopback on the card, and sends a test pattern across the backplane to the card, where it is looped back to the Platform Card and checked for errors Both the data and signaling paths are tested The result of the self-test is reported on the Diagnostics screen Note that you can run a self-test on all of the cards in the system by selecting Shelf Self-Test in the Diagnostic Slot Selection screen Connect a terminal to the TERM port of the Platform Card and configure the Flexi-Voice Plus Card Refer to Local Management - 6 Front Panel Connector Retaining Hardware This hardware consists of a retaining plate and screw attached to a dust cover on the front panel connector, and a captive screw screwed into the standoff just above the connector Remove the captive screw and use it to replace the long screw on the cable connector as shown in Figure 2 Remove the screw and retaining plate from the dust cover, discard the dust cover, and attach the plate to the cable connector as shown The Retaining Plate and the front panel connector clip secure the bottom of the connector and the short screw at the top of the connector screws into the standoff to secure the top Replace Long Screw With Short Screw Standoff Replace the original screw with the captive screw from the standoff Front Panel Retaining Plate Attach the Retaining Plate Connector Clip 50-pin cable Figure 2 50-Pin Connector Retaining Kit 6 GDC 086R

11 Dual OB (FXS) Option Card Compatibility - This option card is supported with all revisions of the Flexi-Voice Plus Card firmware and Platform Card firmware The Dual OB (Originate Battery) option card (Figure 3) provides a two wire voice frequency (VF) interface to telephone equipment such as a telephone set or a PBX trunk Each OB option card has two independently configurable voice channels Features are: signaling for FXS (Foreign Exchange Station) Loop Start or Ground Start, Loop Start or Ground Start with E&M conversion, PLAR (Private Line Automatic Ringdown), and DPO (Dial Pulse Originate) selection of any unused timeslot on LIU A or LIU B TLP default and adjustment settings loopback to network digital milliwatt test tone in a system with a CSU or DSX-1 LIU conditioning to a Forced Idle or Forced Busy state Key Dual OB Option Card 086P MP6360/OB-1 Figure 3 Dual OB Option Card GDC 086R

12 Application Information The Dual OB option card connects to telephone equipment for loop start and ground start applications Note Do not connect the Dual OB option card to lines that go outside the building It is intended for connection to on-premise equipment only Busy/Idle Indication The Busy or Idle state of the OB channel is indicated on the front panel LED for that channel, and on the Local Manager s Flexi-Voice Plus Monitor screen The FXS channel is busy when an off-hook phone causes loop current to flow and initiates an outgoing call towards the network; or for an incoming call, when ringing is being applied to the phone The channel LED will follow the ringing cadence, ie it turns off during the silent interval between rings The channel is idle when no loop current flows and there is no ringing The DPO channel is busy when the loop is seized or when battery polarity is reversed, otherwise it is idle Battery Feed The Dual OB option card provides a battery feed to the telephone loop When the phone is off-hook, this battery feed provides a constant current of approximately 25 ma from a nominal source of 24 VDC This is called Talk Battery Refer to Table 2 of this manual for maximum loop length When the phone is on-hook, the battery feed changes to a higher voltage of about 52 VDC, called Standby Battery The lower Talk Battery voltage reduces power consumption in the off-hook state, and the higher Standby Battery voltage provides compatibility with devices such as some answering machines which require a certain minimum on-hook loop voltage TLP Values The TLP values are entered through the Manager s Flexi-Voice Plus Configuration screen Default 1 (Tx: +30dB, Rx: -90dB) is used for terminating PSTN service This is the setting to use when a telephone or analog PBX trunk is connected to the Dual OB option card over a 2-wire loop with essentially zero cable loss When the voice channel receives a network test tone equal to a digital milliwatt it outputs into the analog voice frequency interface a -9 dbm level When an analog signal with a level of +3 dbm is injected into the voice frequency interface it transmits into the network a digital milliwatt You can adjust these default TLP values from +9 through -3 db (transmit) and from -3 through -15 db (receive) in increments of 01 db Default 2 (Tx: +30dB, Rx: -30dB) is used for dedicated Point-to-Point links where the far end is an FXO This essentially provides a 2-wire to 2-wire extension through the digital network When the voice channel receives a network test tone equal to a digital milliwatt it outputs into the analog voice frequency interface a -3 dbm level When an analog signal with a level of +3 dbm is injected into the voice frequency interface it transmits into the network a digital milliwatt You can adjust these default TLP values from +9 through -3 db (transmit) and from +3 through -9 db (receive) in increments of 01 db 8 GDC 086R

13 Default 3 (Tx: 0dB, Rx:-60dB) is used for terminating PSTN service This is the setting to use when a telephone or analog PBX trunk is connected to the Dual OB option card over a 2-wire loop with 3 db of cable loss When the voice channel receives a network test tone equal to a digital milliwatt it outputs into the analog voice frequency interface a -6 dbm level When an analog signal with a level of 0 dbm is injected into the voice frequency interface it transmits into the network a digital milliwatt You can adjust these default TLP values from +6 through -6 db (transmit) and from 0 through -12 db (receive) in increments of 01 db Standard Loop Start Standard Loop Start is selected through the Manager s Flexi-Voice Plus Configuration screen INTERFACE TYPE:------> FXS/LS SIGNALING MODE: > STND This mode of operation is used when the far end is an FXO loop start card or is network compatible with signaling When the loop is in an idle state (subscriber end equipment is on-hook) standby battery is applied to the loop When the subscriber end initiates a call it seizes the loop (equipment in off-hook state - battery current flows) which signals the network to send dial tone When the far end initiates a call it signals the network telling the Dual OB option card to apply ringing voltage across Tip and Ring The Dual OB option card waits for the detection of loop current (Tip and Ring closure by the subscriber equipment going off-hook) to signal the call connection Standard Ground Start Standard Ground Start is selected through the Manager s Flexi-Voice Plus Configuration screen INTERFACE TYPE: > FXS/GS SIGNALING MODE: > STND This mode of operation is used when the far end is an FXO ground start card or is network compatible with signaling When the loop is in an idle state the subscriber end equipment s Ring lead is not grounded and there is no battery potential across Tip and Ring (open circuit) When the subscriber end initiates a call it grounds the Ring lead which is detected by the Dual OB option card The Dual OB option card then applies battery potential across Tip and Ring This is detected by the subscriber end equipment, which then removes the Ring ground, and provides loop closure This signals the network to send dial tone When the far end initiates a call it signals the network telling the Dual OB option card to close the Tip lead and so provide battery potential across Tip and Ring It also applies ringing voltage to the loop The Dual OB option card waits for the detection of loop current (Tip and Ring closure by the subscriber equipment going off-hook) to signal the call connection When the far end hangs up a call, the Dual OB option card will open the Tip lead after a delay of two seconds This removes Talk Battery from the loop The Tip lead will remain open for at least one second until the next call is initiated GDC 086R

14 Loop Start With E&M Conversion Loop Start With E&M Conversion is selected through the Manager s Flexi-Voice Plus Configuration screen INTERFACE TYPE: > FXS/LS SIGNALING MODE: > CNVSN This mode of operation is used when the far end is an AT&T 4ESS exchange or uses network compatible E&M signaling In this E&M-like mode, there is only a two-state condition of either onhook or off-hook When the loop is in the idle state (subscriber end equipment is on-hook) standby battery is applied to the loop When the subscriber end initiates a call, it seizes the loop (equipment in the off-hook state - battery current flows) which signals the network which returns dial tone When the far end initiates a call, it signals the network telling the Dual OB option card to apply the cadenced (2 seconds On, 4 seconds Off) ringing voltage across Tip and Ring and also to apply Ringback tone to the network The Dual OB option card waits for the detection of loop current (Tip and Ring closure by the subscriber equipment going off-hook) to signal the call connection When the far end hangs up a call, after a delay of two seconds the Dual OB option card will remove Talk Battery from the loop for a duration of one second and then restore it This Forward Disconnect indicates to the subscriber end equipment (modems, answering machines, etc) that the call is terminated Ground Start With E&M Conversion Ground Start With E&M Conversion is selected through the Manager s Flexi-Voice Plus Configuration screen INTERFACE TYPE: > FXS/GS SIGNALING MODE: > CNVSN This mode of operation is used when the far end is an AT&T 4ESS exchange or uses networkcompatible E&M signaling In this E&M-like mode, there is only a two-state condition of either onhook or off-hook When the loop is in an idle state, the subscriber end equipment s Ring lead is not grounded and there is no battery potential across Tip and Ring (open circuit) When the subscriber end initiates a call it grounds the Ring lead which is detected by the Dual OB option card The Dual OB option card then applies battery potential across Tip and Ring which is detected by the subscriber end equipment, which then removes the Ring ground and provides loop closure When the far end initiates a call it signals the network telling the Dual OB option card to apply the cadenced (2 seconds On, 4 seconds Off) ringing voltage across Tip and Ring and also to apply Ringback tone to the network The Dual OB option card waits for the detection of loop current (Tip and Ring closure by the suscriber equipment going off-hook) to signal the call connection When the far end hangs up a call, the Dual OB option card will open the Tip lead after a delay of two seconds This removes Talk Battery from the loop The Tip lead will remain open for at least one second until the next call is initiated 10 GDC 086R

15 PLAR Loop Start PLAR (Private Line Automatic Ringdown) Loop Start is selected through the Manager s Flexi- Voice Plus Configuration screen INTERFACE TYPE: > FXS/LS SIGNALING MODE: > PLAR This mode of operation is used when the far end is an FXS type card with a phone connection This mode provides a hot-line or ringdown application When the loop is in the idle state, subscriber end equipment is on-hook and standby battery is applied to the loop When the subscriber end initiates a call, it seizes the loop (equipment in the off-hook state - battery current flows) which signals the far end to ring the phone When the far end initiates a call it signals the network telling the Dual OB option card to apply the cadenced (2 seconds On, 4 seconds Off) ringing voltage across Tip and Ring and also to apply Ringback tone back to the far end phone The Dual OB option card waits for the detection of loop current (Tip and Ring closure by the subscriber equipment going off-hook) to signal the call connection When the far end hangs up a call, after a delay of two seconds the Dual OB option card will remove Talk Battery from the loop for a duration of one second and then restore it This Forward Disconnect indicates to the subscriber end equipment (modems, answering machines, etc) that the call is terminated DPO Loop Start DPO (Dial Pulse Originate) Loop Start is selected through the Manager s Flexi-Voice Plus Configuration screen INTERFACE TYPE: > DPO SIGNALING MODE: > STND When the loop is in the idle state, the subscriber end equipment is on-hook and the battery polarity is such that Tip is at ground potential and Ring is at battery potential When the subscriber end connects, it seizes the loop (equipment in off-hook state - battery current flows) which signals the far end equipment to seize the loop Answer supervision is passed back by means of signaling the Dual OB option card to reverse the battery polarity The call is terminated when either end goes back on-hook which causes battery polarity to be returned to the normal state Caller-ID The Dual OB option card passes Caller-ID tones, which are sent from the network between ringing signals GDC 086R

16 Diagnostics You can perform a loopback test, generate a digital test tone, or force the voice channel signaling to a known state in order to verify the functionality of the OB channel See Figure 4 Flexi-Voice Plus Card SLIC Dual OB Card (single Channel) CODEC Decoder BACKPLANE 1 khz 0 dbm0 Digital Test Tone Transmit Signaling Platform Card Battery Loopback 1000 hertz 0dBm test tone Encoder from Platform Card Tip Ring VF Interface LIU 66 E-Block Network Figure 4 Flow Diagram - Dual OB card loopback to network Card Self-test Select Card Selftest on the Manager s Flexi-Voice Plus Diagnostics screen The Platform Card generates a test pattern which it sends in turn to each channel of the Flexi-Voice Plus Card Each channel is looped back and the Platform Card checks for the correct return of the pattern This self-test tests both the PCM data and signaling paths and verifies the integrity of the Flexi-Voice Plus Card and backplane The pass or fail results are displayed on the screen Loopback Test The Loopback test loops back the signal received from the network back to the network Connect test equipment at the far end to generate and receive a test tone Correct receipt of the test tone verifies the entire voice path from the far end to the OB channel 12 GDC 086R

17 Activate the loopback through the Manager s Flexi-Voice Plus Diagnostic screen Local Loopback: > ToNet During the loopback test, the channel is set to a Forced Idle state for two seconds, followed by a Forced Busy state Forced Idle causes the signaling towards the network to be the Idle (on-hook) condition which will terminate any call in progress Forced Idle also causes Standby Battery to be applied to the loop Forced Busy causes the signaling towards the network to be the Busy (offhook) state which will prevent new calls from being set up Forced Busy also ignores any receive signaling and causes Talk Battery to be applied to the loop You can change the state from Forced Busy to Forced Idle after the loopback test is in progress by setting Conditioning to FIdle Digital Milliwatt The digital milliwatt test generates a 1000 Hz 0 dbm0 digital test tone in the Platform Card, and sends it to the selected OB channel where it appears on the VF interface The test tone can only be generated by a Platform Card with CSU or DSX-1 LIUs Activate the digital milliwatt test through the Manager s Flexi-Voice Plus Diagnostic screen Dig MWatt: > On The level of the test tone at the VF interface is equal to the receive TLP level For example, if the receive TLP is -3 db, the level of the test tone will be -3 dbm Use external test equipment to verify the correct TLP level When you activate the test, the channel is forced Busy You can change the state from Forced Busy to Forced Idle after the test is in progress by setting Conditioning to FIdle Loopback With Digital Milliwatt On the Manager s Flexi-Voice Plus Diagnostic screen select Local Loopback: > ToNet and Dig MWatt: > On to loop the test tone towards the network to the far end You can use test equipment connected to the channel at the far end to verify the level The test tone still appears at the local VF interface, but at a fixed level of -15 dbm, independent of the receive TLP setting for the channel The level of the test tone towards the network is at a fixed level of -15 dbm0, independent of the transmit TLP setting The conditioning is the same as with the Loopback test Force Busy Next Idle Condition Use this test to remove a Flexi-Voice Plus Card s channel from service without disrupting any calls in progress Select the Force Busy Next Idle condition through the Manager s Flexi-Voice Plus Diagnostic screen Conditioning:------> FBNI After the OB channel has remained in the Idle state (no incoming calls or off-hook requests) for 2 seconds, it is placed in a Forced Busy state Forced Busy Condition GDC 086R

18 Use this test to cause the channel to be in a busy condition, independent of receive signaling or the actual on-hook or off-hook state of the loop Select the Forced Busy condition through the Manager s Flexi-Voice Plus Diagnostic screen Conditioning: > FBusy Forced Busy causes the signaling towards the network to be the Busy (off-hook) state which will prevent new calls from being set up Forced Busy also ignores any receive signaling and causes Talk Battery to be applied to the loop Forced Idle Condition Use this test to cause the channel to be in an idle condition, independent of receive signaling or the actual on-hook or off-hook state of the loop Select the Forced Idle condition through the Manager s Flexi-Voice Plus Diagnostic screen Conditioning: > FIdle Forced Idle causes the signaling towards the network to be the Idle (on-hook) condition which will terminate any call in progress Forced Idle ignores any receive signaling and also causes Standby Battery to be applied to the loop 14 GDC 086R

19 Dual TB (FXO) Option Card Compatibility - This option card is supported with all revisions of the Flexi-Voice Plus Card firmware and Platform Card firmware The Dual TB (Terminate Battery) option card (Figure 5) provides a two-wire voice frequency (VF) interface to CO subscriber lines or to PBX extension lines Each TB option card has two independently configurable voice channels Features are: signaling for Loop Start or Ground Start, and DPT selection of any unused timeslot on LIU A or LIU B 600 or 900 ohm termination TLP default and adjustment settings loopback towards the network digital milliwatt test tone in a system with a CSU or DSX-1 LIU conditioning of the channel to a Forced Idle or Forced Busy state Key CH 1 CH 2 X1 X2 X3 X default position Dual TB Option card 086P MP6360/TB-1 Before installing the TB option card onto the basecard, select the type of termination for each channel using jumpers X1, X2, X3, and X4 The 600 ohm termination is the most common After the card has been properly installed, you can verify the setting through the Manager s Flexi-Voice Plus Monitor screen Impedance: (OHMS) > * 600 or 900 Figure 5 Dual TB Option Card Application Information Busy/Idle Indication The Busy or Idle state of the TB channel is indicated on the front panel LED for that channel, and on the Local Manager s Flexi-Voice Plus Monitor screen The channel is busy when an incoming call from the network causes the Dual TB option card to go GDC 086R

20 off-hook; or when ringing is detected by the Dual TB option card to initiate an outgoing call Note that the LED will follow the ringing cadence, ie it will turn off during the silent interval between rings The channel is idle when the Dual TB option card is on-hook and there is no ringing detected by the card TLP Values The TLP values are entered through the Manager s Flexi-Voice Plus Configuration screen Default 1 (Tx: +3 db, Rx: -3 db) is used for dedicated Point-to-Point links where the far end is an FXS This essentially provides a 2-wire to 2-wire extension through the digital network When the Dual TB option card receives a network test tone equal to a digital milliwatt it outputs into the analog voice frequency interface a -3 dbm level When an analog signal with a level of +3 dbm is injected into the voice frequency interface it transmits into the network a digital milliwatt You can adjust these default TLP values from +9 through -3 db (transmit) and from -1 through -9 db (receive) in increments of 01 db Default 2 (Tx: 0 db, Rx: -9 db) is used for terminating PSTN service When the Dual TB option card receives a network test tone equal to a digital milliwatt it outputs into the analog voice frequency interface a -9 dbm level When an analog signal with a level of +0 dbm is injected into the voice frequency interface it transmits into the network a digital milliwatt You can adjust these default TLP values from +6 through -6 db (transmit) and from -3 through -15 db (receive) in increments of 01 db Standard Loop Start Standard Loop Start is selected through the Manager s Flexi-Voice Plus Configuration screen INTERFACE TYPE:------> FXO/LS SIGNALING MODE: > STND This mode of operation is used when the far-end is an FXS loop start card or is network compatible with signaling When the loop is in an idle state, the office end equipment (exchange) provides a battery with Tip at ground and Ring at the battery potential The Dual TB option card is on-hook which presents a high impedance to the loop (no battery current flowing) When the office end equipment (exchange) initiates a call it applies a ringing voltage to the Dual TB option card This ring detection by the Dual TB option card signals the far end (through the network) which allows the FXS card to apply a ringing voltage to the phone When the far end goes off-hook the network signaling allows the Dual TB option card to go off-hook thus completing the call When the far end initiates a call it goes off-hook which signals the network telling the Dual TB option card to seize the loop (TB off-hook) The office end equipment (exchange) sends dial tone Standard Ground Start Standard Ground Start is selected through the Manager s Flexi-Voice Plus Configuration screen INTERFACE TYPE: > FXO/GS SIGNALING MODE: > STND 16 GDC 086R

21 This mode of operation is used when the far end is an FXS ground start card or is network compatible with signaling When the loop is in an idle state the office end equipment opens the Tip lead and there is no battery potential across Tip and Ring The Dual TB option card is on-hook which presents a high impedance to the loop When the office end initiates a call it supplies a ringing voltage to the Dual TB option card This ring detection by the Dual TB option card signals the far end (through the network) which allows the FXS card to apply a ringing voltage to the phone When the far end goes off-hook the network signaling allows the Dual TB option card to go off-hook thus completing the call When the far end initiates a call it receives a Ring ground that signals the network telling the Dual TB option card to ground the Ring lead to the office equipment The office end equipment reacts to the Ring ground by applying Tip ground which the Dual TB option card detects and signals the farend (through the network) to apply Tip ground to its interface When the far-end seizes the loop (goes off-hook) it signals (through the network) the Dual TB option card to remove Ring ground and go off-hook thus completing the connection DPT DPT (Dial Pulse Terminate) is selected through the Manager s Flexi-Voice Plus Configuration screen INTERFACE TYPE: > DPT SIGNALING MODE: > STND One common application for DPT is for DID (Direct Inward Dialing) service The Dual TB option card connects to a PBX trunk which provides battery (Tip at ground potential and Ring at battery potential) An incoming call from the network causes the Dual TB option card to seize the loop The PBX detects loop current and responds by toggling the polarity of the battery to transmit a wink to the network The network then sends dial pulses to dial the PBX extension Dial pulses are transmitted by the Dual TB option card by opening and closing the loop GDC 086R
