Drop & Insert and tdm-group

My environment: Cisco 2821 router

IOS version: c2800nm-adventerprisek9-mz.124-24.T.bin

VWIC card: VWIC2-2MFT-T1/E1

Drop & Insert (D & I)

  • Circuit switching
  • DSP NOT used
  • Cross-connecting TDM circuits from one port to another port
  • Individual 64kbps DS0 channel can be transparently passed. uncompressed between T1/E1 ports without DSP processing
  • Simply provides a TDM backplane and connect 2 controllers together
  • Need to use the SAME framing type on both controllers

Example:

BB3#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
BB3(config)#controller e1 0/0/0
BB3(config-controller)#framing crc4
BB3(config-controller)#linecode hdb3
BB3(config-controller)#tdm-group 1 timeslots 1-8 type e&m
 
BB3(config)#controller e1 0/0/1
BB3(config-controller)#framing crc4
BB3(config-controller)#linecode hdb3
BB3(config-controller)#tdm-group 2 timeslots 1-8 type e&m

BB3(config)#connect d_and_i e1 0/0/0 1 e1 0/0/1 2
