1 6, 7/8, 0/ GHz ANSI digital hierarchy Constellation point-to-point digital radio NEW! More System Options and a 4xDS Interface! Constellation is a scalable low, medium, and high capacity digital radio that provides reliable transport from 8xDS to OC, OCc, xds and STS. Save money and shelter space with Constellation's new 4xDS interface, which provides greater capacity in the same footprint. This new interface is backwards-compatible, enabling operators to perform field upgrades and add another DS without adding another radio. Constellation s interfaces offer a high system gain option, which lowers cost for additional antennas and monthly tower space rentals, and achieves greater path reliability. The high system gain option has been expanded to include and 8xDS/xDS interfaces, giving even more network planning flexibility. Designed for high-performance, lowcost networking applications, Constellation is the ideal solution for wireless carrier and private network operators. It is an affordable, flexible, compact and reliable package featuring convenient and robust operation, fast installation and easy maintenance. Constellation provides the capability for field upgrades from low to high capacity. The xds arrangement offers an optional xds + 8xDS interface with an integrated multiplexer, providing DS access from a DS at terminals and add/drop repeaters with no need for external M multiplexers. The 4xDS arrangement offers an optional xds + 8xDS interface with Constellation's integrated multiplexer. Antenna coupling unit options offer a wide variety of optimal RF transmission architectures as well as expansion ports that easily accommodate parallel paths for capacity expansion. A rich feature set delivers maximum system gain, superior T/I values to facilitate frequency coordination, protection from far-end transmitter and antenna feeder system degradations through reverse channel switching, and security from fading effects and module degradations using powerful FEC, adaptive time domain and slope amplitude equalizers. Flexible, versatile monitoring and control is provided through an embedded SNMP agent that is compatible with Harris NetBoss, StarView and FarScan platforms. An easy-to-use craft interface is provided for convenient operation via a user s laptop computer or an optional keypad, allowing full network visibility to card level from a single site. Maintenance tasks are simplified with remote software download and inventorying capability, and easy module replacement with redundant configuration storage.

Easy-to-use craft interface via laptop or optional; keypad, allowing full network visibility to card level from a single site. Antenna coupling unit expansion port allows addition of radios on existing antenna feeder systems. NEW! 4xDS Interface No need for another radio to add the next DS. Greater value for investment at new installations with more capacity in the same footprint. All Constellation radios can be upgraded. The fourth DS is accessed through an existing BNC connecter on backplane. Perform a cost-effective capacity upgrade in the field simply by swapping components. xds + 8DS interface with integrated add/drop multiplexer. Network Management Interfaces SNMP, FarScan, NetBoss, StarView, handheld keypad, dry contact alarms. Recommended Test Equipment Digital multimeter (to test battery voltage and align antenna). Frequency counter (to adjust frequency of Tx or ). Power meter and power sensor (to check Tx power output). Convenient (or )xds + 8xDS Interface xds radio provides xds + 8xDS interface by simply adding M cards. Select any one of the xdss for access to 8xDSs. Similarly, 4xDS radio provides xds + 8xDS interface, with any one of the first xdss selectable for access to 8xDSs. No external M MUX is required. The same DS does not have to be selected from site to site. An add-drop mode is provided in a back-to-back terminal arrangement. Features include: Up to 6 DSs can be added/dropped in DS groups of 4 DSs. The DS that is selected for add/drop is interconnected at the DS level. All non-dropped DSs are passed through in the DS. M cards are used only for DSs that are added/dropped. The M Cards are :N protected. Non-dropped DSs can pass through up to 8 consecutive add/drop hops before they are required to drop. DSs can pass through 5 hops before they are required to drop.

4 Optional Paperless Chart Recorder Constellation s Paperless Chart Recorder (PCR) Option displays main (A) and diversity or hot-standby (A) receiver RSL s (receive signal levels) as well as alarm, Tx/ switching activity, and DS/OC- tributary performance (ES, SES outage) history. Registers in Constellation s SPU Controller card store this data over weeks and months. The PCR Data Loader program uploads these continuously collected data from each SPU Controller card at the radio or remotely from any site in a contiguous network. The PCR History Data Viewer can exhibit All Data over the current PCR data collection period, as seen below, or it can exhibit data for smaller time periods, such as a - or -day, a -, -, or -hour, or a - or 5-minute screen display along with A and A receiver RSL s for a much more detailed and exacting examination. PCR is a powerful diagnostic tool that collects and displays each receiver s FEC, modem, signal degrade, and eye quality alarms, transmitter switching (on-line) due to RCS (reverse channel switch) and keypad commands, errorless receiver data switching (on line), and DS or OC- error performance (ES and SES outages). These events are easily correlated with selective, flat, and dispersive (spectrum-distorting) fade activity, interference, maintenance activity, and module behavior for total visibility over each Constellation link. Following are two PCR History Data Viewer screens showing All Data (about week) of main (A) and diversity (A) receiver fade activity, alarms, errorless data switching, and tributary DS errored seconds (0) and SES outages (0) uploaded from each direction of a heavy fading Constellation 0 GHz overwater link. 4
