to an external LAN hub or switch. You can use this connector to
isolate T1 traffic. If the T1 Digital Line Card is used in a V5000
Gateway Chassis, do not use this connector because the chassis has
an Ethernet connector to connect the chassis to the LAN.

terminal connection for maintenance access.
CAUTION: This equipment does not operate when the main power fails.
The E1 Digital Line Card provides E1 connectivity using the ISDN PRI
protocol. It carries data at a rate of 2.048 Mbps and can carry 32
channels, each with 64 Kbps. Thirty of these channels are available for
calls. Like the T1 ISDN PRI Card, the E1 PRI Card supports PRI software
features such as DID.
