IBM SC30-3681-08 manual Frame-type, For T1 PRI, Default Value a, Default Values B8ZS

ISDN Con®guration Commands

included. You must set the ISDN frame size so that it is greater than or equal to the frame size con®gured for the dial circuits using the ISDN interface.

For PPP dial circuit interfaces, you can change the PPP MRU using the set lcp options command. The ISDN frame size must include enough bytes for the PPP MRU and the PPP header.

Note: If you choose a frame size of 1024, PPP will not work over the ISDN dial circuit, since the minimum frame size for PPP is 1500.

For FR dial circuit interfaces, you can change the frame size using the set framesize command. The ISDN frame size must be greater than or equal to the FR frame size.

If a dial circuit's frame size is greater then the ISDN frame size, then the dial circuit's frame size is decreased at router initialization.

Example:

set framesize

Framesize in bytes (1024/2048/4096/8192) [1024]? 2048

frame-type

Choices are D4 or ESF. This speci®es the T1 multiframe format. Only ESF is supported for non-channelized mode. Frame type is con®gured under the base ISDN net menu.

Example:

set frame-type

Circuit config: 10>set frame type

interface
