8-Port Channelized T1/E1 SPA Overview
8-Port Channelized T1/E1 Serial SPA Interface Specifications
The E1 interface on the 8-Port Channelized T1/E1 Serial 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.
Caution Shielded T1/E1 cables must be used to comply with FCC/EN55022/CISPR22 Class A emissions
requirements.
