MIX 56

Telect’s Multiplexer with Integrated Cross-Connect, 56 Circuit (MIX 56) chassis houses two fully independent systems, each with 28 DSX jacks and up to two M13 multiplexer cards. Each system can be used as a DSX only, as a nonredundant multiplexer, or as a redundant multiplexer.

When used as a DSX only, a system can be cabled quickly using the rear 64-pin connectors and provides full DSX functionality, including patching and monitoring, using the DSX jacks on the chassis front.

When a single M13 card is added, a system becomes a nonredundant multi- plexer/demultiplexer, which combines 28 DS1 or 21 E1 signals into a sin- gle industry standard DS3 signal and separates a DS3 signal into 28 DS1 or 21 E1 signals.

Adding a second card provides 1:1 redundancy for all M13 functionality. The 28 DS1 low-speed channels and the DS3 high-speed interfaces reside on one M13 card occupying one card slot, while the protection card occu- pies the second card slot. The two cards are in constant communication, and all configuration changes made to the active card are also automatical- ly made to the standby card.

Redundant and nonredundant multiplexer applications include full DSX functionality when DS1 wiring is connected to the wire-wrap pins on the front of the chassis, rather than to the rear 64-pin connectors.

Configuration, diagnostics, and performance monitoring are performed us- ing SNMP through the Ethernet port, or using the Craft interface either re- motely with Telnet through the Ethernet port or locally through the RS-232 Craft port.
