QuestionQ341

Voice Gateways and Session Border Controllers

Question Image

Refer to the exhibit. An engineer is troubleshooting an E1 interface module that fails to come up. The E1 module must use these configurations:

  • The linecode type must be Alternate Mark Inversion.
  • The frame type must be Extended Super Frame.
  • All available channels must be used.

An engineer has already deployed the configurations shown in the exhibit to the Cisco voice gateway. Which additional configuration must be performed to resolve the issue?

  • A controller E1 0/2/0pri-group timeslots 1-31
  • B controller E1 0/2/0pri-group timeslots 1-23
  • C interface E1 0/2/0:31pri-group timeslots 1-31
  • D interface E1 0/2/0:23pri-group timeslots 1-23
Explanation

A full E1 ISDN PRI is configured under the E1 controller with pri-group timeslots 1-31. The range includes the complete E1 timeslot set, with timeslot 16 serving as the D channel; 1-23 is the full T1 range, not E1.
