Description
Provides 75/120 ohm impedance matching for 21 E1 Circuits. Coaxial connectors can be specified as BNC, Type43 (BT) or 1.6/5.6 (Small Siemens). Twisted pair connectors are female 50 way Telco (Amp Champ), one for the transmit circuits, the other carries the receive circuits, as per Adtran's MX2800 STS-1 Access MultiplexerTM and the Carrier Access Wide Bank 28 DS3TM specifications. Please advise us if you require a different wiring scheme.

Cables are available for connecting to the Adtran MX2800 STS-1 and the CarrierAccess Wide Bank 28 DS3. Only occupying 1U rack space in a standard 19" rack, with reversible mounting ears, an optional 23" mounting kit is also available. Designed to meet or exceed CCITT G.703 Specifications for bi-directional signal conversion, at data rates from 2.048 to 8.448Mbit/s.
