Channelized T1 IQ PIC
■JUNOS 7.4 and laterSoftware release
■Ten T1 ports
■Power requirement: 0.15 A @ 48 V (7.2 W)
■Intelligent queuing (IQ) PICs support fine-grained queuing per logical interface.
■Channelization: T1, FT1, NxDS0
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)
