Configuring WAN interfaces
Note:
Use the cablelength command to configure the cable's transmit and receive
Note:
levels. If the cable is longer than 655 feet, use the command cablelength
long gain26|gain36 -15db|-22.5db|-7.5db|0db (default gain26, 0db).
If the cable is 655 feet or less, use the command cablelength short
133ft|266ft|399ft|533ft|655ft (default 133ft). When using the
cablelength short form of the command, the transmit attenuation is
configured using the loop length.
- For E1 mode:
clock source line|internal (default is line)
framing crc4|no-crc4|unframed (default is crc4)
linecode ami|hdb3 (default is hdb3)
6. Use the channel-group command to specify the channel group and time slots to be
mapped, as well as the DS0 speed. For example:
- For T1 mode:
channel-group 1 timeslots 1,3-5,7 speed 64
configures time slots numbered 1, 3-5 and 7 to be mapped in channel-group number 1,
and sets the DS0 speed to 64 kbps. The default DS0 speed for T1 mode is 56.
- For E1 mode:
channel-group 1 timeslots 1,3-5,7 speed 64
configures time slots numbered 1, 3-5, and 7 to be mapped in channel-group number
1, and sets the DS0 speed to 64 kbps. The default DS0 speed for E1 mode is 64.
Note:
The G250 only supports a single channel group.
Note:
7. Type exit to return to general context. The prompt returns to:
G350-001(super)#
8. Use the interface Serial command to enter the context of the interface. Specify the
slot number of the media module, the port number, the channel group number, and
optionally, the IP interface number.
Note:
The WAN media module in a G250 must always be in slot number 2. The G250
Note:
only supports a single channel group.
