7705 SAR-A Ports

T1/E1 Ports

On the 7705 SAR-A variant equipped with T1/E1 ports, there are eight RJ-45 connectors on
the front of the chassis that provide 100 Ω T1 or 120 Ω E1 access to the T1/E1 ports. The
T1/E1 ports can be used only for access connectivity.
Use shielded RJ-45 cables to attach customer equipment to the 7705 SAR-A T1/E1 ports.
Shielded cable must be used to maintain EMC compliance. The T1/E1 ports are on-premises
ports and require an external CSU to connect off premises. An adapter cable (3HE04990AA)
is available to convert an RJ-45 connector to BNC for E1 ports; these ports must be
configured for 75 Ω impedance.
