The Allied Telesyn iMAP chassis is designed to provide the highest possible quality, reliability and performance to our customer’s networks. The CFC is key to the 99.999% carrier grade reliability and is designed to operate in a redundant hot standby mode or simplex mode. In the iMAP 9700 chassis the CFC supports up to 17 service cards. In the iMAP 9400 chassis the CFC-24 supports 7 service modules.The CFC-24 supports both 100Mbps or 1Gbps to each backplane slot allowing it to supports all Allied Telesyn iMAP service modules. The CFC-24 supports up to 6-1GE links for network interface, high reliability EPSR rings or subtending. While providing this transport, the iMAP CFC-24 continues to provide highly reliable service access. When a network requires EPSR rings or
subtending all management and control is completed on the CFC-24. The CFC handles anagement, configuration and monitoring of all cards in the chassis. Operators may access the CLI via RS-232 or
use 100Mbps or Inband for Telnet operation. The Allied Telesyn Network Management System (NMS) may access the CLI or SNMP interface via 100Mbps or Inband.Telnet and the NMS provide simple user interface for all operations, administration and performance monitoring.The CFC-24 maintains all card and shelf configuration in a local FLASH database. Performance monitoring information on all network and service interface is gathered, stored and available to the OAM interfaces. The CFC-24 supports Compact FLASH Type II. This FLASH may be used to install new
software upgrades, logging information, etc. Service redundancy is provided through the TN-401. When redundant, the active CFC maintains the database and information on the “hot standby” CFC. The unique design of the iMAP chassis, the CFC and CFC software allows the backup CFC to
maintain current up to date information of all switching and forwarding decisions.This allows a
CFC switchover between the active and backup to be instantaneous to minimize packet loss.
This type of carrier grade design provides service providers the reliability they have come to expect.
