Chapter 1 Overview of the Cisco 3825 Mobile Wireless Edge Router New Features in Cisco IOS Release 12.4(16)MR1 Use the time slots keyword and the timeslot-range argument to specify the time slots to be included in the CEM channel. The list of time slots may include commas and hyphens with no spaces between the numbers, commas, and hyphens. The following example illustrates the use of the cem-group command: SATOP controller el 0/0/0 cem-group 0 unframed int cem 0/0/0 cem 0 xconnect 10.10.10.10 200 encap mpls CESoPSN controller e1 0/0/1 cem-group 0 timeslots 1-31 int cem 0/0/1 cem 0 xconnect 10.10.10.10 200 encap mpls A new command sample-rate has been added to this feature to specify in milliseconds the rate that hardware samples data on the attached circuit. The default is 1 ms. The sample-rate command translates into the payload-size that is sent over the circuit. • 32-time slots at 1 ms = 256-bytes (32-time slots * 8-bytes/timeslot/ms) • 24-time slots at 2 ms = 384-bytes (24-time slots * 16-bytes/timeslot/ms) • 10-time slots at 1 ms = 80-bytes (10-time slots * 8-bytes/timeslot/ms) The following example illustrates the use of the sample-rate command: interface CEM0/0/0 no ip address cem 0 sample-rate 2 xconnect 10.10.10.10 200 encapsulation mpls A new command dejitter-buffer has been added to this feature to specify the size of the dejitter-buffer used to compensate for the network jitter. • Use the size argument to specify the size of the buffer in milliseconds. • Size can vary from 4 - 500 ms; default is 4 ms. The following example illustrates the use of the dejitter-buffer command: interface CEM0/0/0 no ip address cem 0 dejitter-buffer 10 xconnect 10.10.10.10 200 encapsulation mpls A new command idle-pattern has been added to this feature to specify the data pattern transmitted on the T1/E1 when missing packets are detected on the PWE3 circuit. The default idle-pattern command is 0xFF. OL-15667-03 Cisco 3825 Mobile Wireless Edge Router Software Configuration Guide 1-15
