Note: Command history is very useful for repeating commands. Press the Up-Arrow to 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)
