Note:
Note:
Use the
cablelength
command to configure the cable’s transmit and receive
levels. If the cable is longer than 655 feet, use the command
cablelength
long gain26|gain36 -15db|-22.5db|-7.5db|0db
(default is gain26,
0db). If the cable is 655 feet or less, use the command
cablelength short
133ft|266ft|399ft|533ft|655ft
(default is 133ft). When using the
cablelength short
form of the command, the transmit attenuation is
configured using the loop length.
●
fdl ansi|att|both
(default is both)
Note:
Note:
The
fdl
command defines the type of Facility Data Link loopback that the
remote line is requested to enter. This command can only be used when ESF
framing is defined.
- 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:
Note:
The G250 only supports a single channel group.
7. Enter

to return to general context. The prompt returns to:
8. Use the
interface serial
command to enter the
Serial
interface context. Specify
the slot number of the media module, the port number, the channel group number, and
optionally, the IP interface number.
