Description  

The Loop-V 4200-28 IMAP is a versatile device with 3 high speed and 28 low speed slots. Depending on the plug-in cards selected, this unit can be configured (a) as an OC3 (STM1/STS3) access device, (b) as a T1/E1 CSU/DSU with drop and insert and voice capabilities, (c) as an E1 to T1 converter (or fractions of them), (d) as a digital cross-connect system (DACS), and (e) as a channel bank. As a CSU/DSU, data from the V.35 or X.21 port can occupy any fraction of an E1 or T1 port. As an E1 to T1 converter, A to img law and signaling conversions are correctly handled. For both E1 and T1 ports, continuous error checking, performance polling, and in-service diagnostics are provided. In any of the above combinations, full time slot interchange (TSI) among the ports are possible, making the Loop-V 4200-28 a small DACS (digital access cross-connect system). All the low speed ports can be muxed to the high speed ports.

The Loop-V 4200-28 supports local control and diagnostics by using a VT-100 terminal connected to the console port. The Loop-V 4200-28 also supports Ethernet, Telnet, and SNMP, so it can be controlled and diagnosed from remote locations. The Loop-V 4200-28 also supports inband Management, where management data is carried the same way as user data, traversing national networks.

Multicolor LEDs provide status indication for power, test condition, and alarm for each of the ports. Internal firmware is stored in flash memory so that future firmware upgrades can be downloaded.
