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.
