redisplay the command, and then press Enter. (For more information, see the TAOS
Command-Line Interface Guide.)
Configuring nailed channels
The number of nailed (leased) channels must be the same at both ends of the connection. For
example, if there are five nailed channels at the local end, there must be five nailed channels at
the remote end. However, channel assignments do not have to match. For example Channel 1
might be switched at the local end and nailed at the remote end.
Note that channels in a nailed group must be contiguous on the T1 line.
When you configure Connection profiles to use the leased connection, you must specify the
Nailed-Group number in the Telco-Options subprofile.
To configure a nailed channel, proceed as in the following example:
admin> list line channel 1
channel-usage = switched-channel
trunk-group = 9
phone-number = ""
call-route-info = { any-shelf any-slot 0 }
nailed-group = 0
admin>
set channel = nailed
admin> set nailed = 3
admin> list .. 2
channel-usage = switched-channel
trunk-group = 9
phone-number = ""
call-route-info = { any-shelf any-slot 0 }
nailed-group = 0
admin>
set channel = nailed
admin> set nailed = 3
admin> write
Configuring a back-to-back T1 connection
For diagnostic purposes, you might sometimes want to configure a back-to-back T1
connection between ports on two TAOS units. In the T1 profile for one end of the line you
want to connect with a back-to-back connection, specify the following values:
• Signaling-Mode set to Inband (the default)
• Robbed-Bit-Mode set to Wink-Start (the default)
