8-Port Channelized T1/E1 SPA Interface Specifications

The E1 interface on the 8-Port Channelized T1/E1 SPA uses RJ-48c receptacles for E1 (120-Ohm) cables
with RJ-45 connectors. You can use all ports simultaneously. Each E1 connection supports interfaces that
meet G.703 standards. The RJ-45 connection does not require an external transceiver. The E1 ports are
E1 interfaces that use 120-ohm shielded twisted pair (STP) cables.
