Description
■
Data service unit (DSU) and channel service unit (CSU) functionality
■
Ports configurable as clear channel T1 interfaces with 1.544-Mbps connectivity
■
Framing: Superframe (SF or D4) and Extended Superframe (ESF)
■
Supports B8ZS (bipolar 8-zero substitution) and AMI (alternate mark inversion) line coding
■
Local, remote, and payload loopback testing
■
ANSI T1.403 loopback support:
■
Responds to embedded loopback commands upon receipt of an FDL command
from remote end with loopup and loopdown at both line and payload level
■
Insertion of loopback commands enables remote CSU/NIU/Smartjack to enter
loopback and loopdown at both the line and payload level (ANSI and Telcordia)

Inband loopback support:
■
Responds to inband loopback commands at both the line and payload level (ANSI
and Telcordia)
■
Insertion of inband loopback commands at both the line and payload level (ANSI
and Telcordia)
■
Clocking support of external (line) and internal
■
Buildout support of the following ranges:
■
0 through 132 (Line buildout is from 1 through 132 feet)
■
133 through 265 (Line buildout is from 133 through 265 feet)
■
266 through 398 (Line buildout is from 266 through 398 feet)
■
399 through 531 (Line buildout is from 399 through 531 feet)
■
532 through 655 (Line buildout is from 532 through 655 feet)
