MAINTENANCE SUPPORT
for Prologix with Avaya Communication Manager or Avaya Software and a CMC Media Gateway

The Prologix can be used at a single site or be networked in multiple locations. For example, a Prologix might provide a solution for a satellite office within a larger business or branch locations around the world. Multi-site companies can use remote diagnostics and alarming to maintain the Prologix from a central location. An administrator can centrally administer the system from a central location by using a system administration tool.

Detailed description
High-level description of the Prologix:

• Ideal for small single sites, multi-site locations, and branch locations
  
• Supports up to 1300 ports
  
• Supports 400 trunks and 900 stations
  
• Uses Avaya Communication Manager
  

Configuration information
A Prologix consists of the following main components:

• TN2402 Processor board
  
• TN2182 Tone Clock
  
• CMC1 Media Gateway
  

The following sections describe each component.

TN2402 Processor board
A TN2402 Processor board resides in slot one of cabinet A. This board contains 32 MB of DRAM memory and 32 MB of flash memory. The software is stored on flash memory and on removable memory through Flash-ROM that plugs directly into the TN2402 processor board. The memory on the Processor board contains the generic program and the system translations. The cartridge contains a copy of the system translations and error log. The TN2402 also provides:

• A 5-volt ATA PC-card Memory Card interface
  
• Three external RS232 interfaces [CD1]
  
• A SAT terminal interface
  
• An SMDR / Printer or other DTE interface
  
• A connection for an external modem to dial out alarms
  

Tone-Clock (TN2182)

For any system-reliability configuration, a TN2182B Tone-Clock integrates the tone-generation, tone-detection / call-classification, system-clocking, and synchronization functions onto a single circuit pack. The TN2182 supports eight ports for tone detection and allows gain or loss applied to PCM signals that are received from the bus.

CMC1 Media Gateway
A CMC1 Media Gateway has the following characteristics:

• The size is 25.5 inches wide, 24.5 inches high, and 11.3 inches deep. It is designed for wall mounting. Mounted on the floor or on a table where required.
  
• Ten universal port slots plus one power supply slot per CMC1.
  
• Standard-reliability option only.
  
• Is limited to one PN that is made up of a maximum of three CMC1 Media Gateways. A PN consists of a control CMC1 that is designated "A". The second and third CMC1s are optional and are designated cabinets "B" and "C" respectively. Cabinet address ID within the PN is set using the DIP switch on the backplane.
  
• Circuit packs are inserted and removed from the left side. Cabinet I/O is from the right side.
  
• The CMC1s in a port network are interconnected via shielded TDM/LAN bus cables.
  
• The CMC1 is AC-powered only. There are no internal batteries, and no DC power option.
  
• Two 12-volt DC variable-speed fans integrated into the bottom of the cabinet provide CMC1 cooling. The fans force air through a filter and up through the cabinet. Air exits from the back of the cabinet. Speed control is provided by the 650A Global Power supply. The 650A varies the fan input voltage between 8VDC and 14VDC depending on a temperature sensor that is mounted in the power supply. The fan assembly includes the two fans, a frame to which the fans are attached, wiring, and a connector that plugs into the backplane. The assembly is easily installed and removed. The entire assembly must be replaced as a unit if a fan fails.
  

A fan failure will result in the following conditions:

• An alarm through the power supply that will appears to the system
  
• The remaining fan goes to high speed
  
• The red LED on the 650A Global Power supply faceplate lights
