Release Information
Command introduced before JUNOSe Release 7.1.0.
Description
Configures a loopback for a T1 channel on a DS3 signal. This command applies to a
T1 channel on a DS3 over channelized SONET interface. The
no version turns off
the loopback.
Options
■
pathChannel —Number, in the range 1–2147483648, that identifies the path
■
ds3Channel —Number, in the range 1–3, that identifies the DS3 channel
■
t1Channel —One or more individual T1 channels, ranges of T1 channels, or
combination of individual channels and ranges, in the range 1–28 (no spaces);
for example, 3,7-15,19-13,27
■
local—Loops the router output data back toward the router at the T1 framer; on
supported line modules also sends an alarm indication signal (AIS) out toward
the network.
■
network { line | payload }—Specify the line keyword to loop the data back
toward the network before the T1 framer and automatically set a local loopback
at the HDLC controllers. Specify the
payload keyword to loop the payload data
back toward the network at the T1 framer and automatically set a local loopback
at the HDLC controllers.
■
remote line fdl ansi—Sends a repeating 16-bit ESF data link code word (00001110
11111111) to the remote end requesting that it enter into a network line loopback.
Specify the
ansi keyword to enable the remote line FDL ANSI bit loopback on
the T1 channel, according to the ANSI T1.403 specification.
■
remote line fdl bellcore—Sends a repeating 16-bit ESF data link code word
(00010010 11111111) to the remote end requesting that it enter into a network
line loopback. Specify the
bellcore keyword to enable the remote line FDL
Bellcore bit loopback on the T1 channel, according to the Bellcore TR-TSY-000312
specification.
■
remote payload [ fdl ] [ ansi ]—Sends a repeating 16-bit ESF data link code word
(00010100 11111111) to the remote end requesting that it enter into a network
payload loopback. Enables the remote payload FDL ANSI bit loopback on the T1
channel. You can optionally specify
fdl and ansi , but it is not necessary.
