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
