The ThinMux chassis provides a compact 1U platform for the ThinMux
family of multiplexers with the following interconnects:
• One 10/100BASE-T Ethernet (IEEE 802.3)
• Two 64-pin female receptacle connectors for T1/E1 transmit/receive,
chassis-shielded
•
Four 75 BNC connectors for DS3/STS-1 transmit/receive
•
Four wire-wrap 0.045-inch pins for Building Integrated Timing Supply
(BITS) A and B
•
Four wire-wrap 0.045-inch pins for T1 or E1 test access, transmit/receive
•
Four wire-wrap 0.045-inch pins for Visible (VIS) and Audible (AUD)
alarms (dry relay contacts) which are normally open (NO) discrete
alarms
•
Five wire-wrap 0.045-inch pins for discrete alarms (solid sate relay
contacts): Far End, Minor, Major, and Critical
• Five screw connectors for -48V dual power
• One DB-9 connector for RS-232 communication
