included. You must set the ISDN frame size so that it is greater than or
equal to the frame size configured 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 specifies the T1 multiframe format. Only ESF
is supported for non-channelized mode. Frame type is configured under the
base ISDN net menu.
Example:
set frame-type
Circuit config: 10>set frame type
interface
For PRI only. Sets the following interface parameter values for T1 and E1
lines.
For T1 PRI:
lbo The attenuation of the signal transmitted by the router’s T1 port.
