10/100 Mb hub or switch.

switch.

10/100 Uplink — This RJ-45 Ethernet connector connects the E1 card
to an external LAN hub or switch. You can use this connector to
isolate E1 traffic. If the E1 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.
Console — This DB-9 connector provides an RS-232 (DCE) TTY
terminal connection for maintenance access.
If you require an alternative (bare wire-end) cable to use with the ISDN
PRI Digital Line Card, contact your 3Com NBX Voice-Authorized Partner.
CAUTION: This equipment does not operate when the main power fails.
