Cables, Connectors, and Pinouts
The T1/E1 interface receptacles on the PA-VXA, PA-VXB, and PA-VXC port adapters are for RJ-45
connectors for both T1 (100 ohm) and E1 (120 ohm).
After you properly connect a port to a line, it takes approximately 30 seconds for the Cisco IOS to report
that the line is up.
Each connection supports T1(100-ohm) or E1(120-ohm) interfaces that meet T1.403 and ACCUNET
TR62411 standards. The RJ-45 connection does not require an external transceiver. The DS1 ports are
T1 interfaces that use foil twisted-pair cables.
Shielded cables (foil twisted-pair [FTP]) with 120-ohm impedance are required to comply with CE
marking requirements.
