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.
Caution
Shielded twisted pair (STP) T1/E1 cables must be used to comply with EN55022/CISPR22 Class A emissions
requirements. For revisions 73-8358-05 through 73-8358-08 Shielded Twisted pair (STP) T1/E1 cables must
be used to comply with FCC Class A emissions requirements.
