Juniper Networks Juniper M-series M10i - Manual (Page 30)

Channelized T1 IQ PIC
■ JUNOS 7.4 and later Software 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)
