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.
