Configuring WAN interfaces
3. Use the controller ds-mode slot/port command to enter controller context for the
port to be configured. The prompt changes to:
G350-001(super-if:Serial s/p)#
where s is the slot number of the media module, and p is the port number.
4. Use the following commands to change the clock source, frame type, linecode, or cable
length parameters from the default settings:
- For T1 mode:
clock source line|internal (default is line)
framing sf|esf (default is sf)
linecode ami|b8zs (default is ami)
cablelength long|short (default is long, gain26, 0db)
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)
5. 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.
