T Lite Single-Port T1 CSU
T Lite is a Single-port, frame-transparent T1 CSU. It can detect and activate network initiation loopbacks, monitor bipolar violations, and maintain pulse density of the transmitted signal. The unit is transparent to framed (D4 or ESF) or unggramed T1 signals and can operate in either AMI or B8ZS line coding mode.
2000 Single-Port T1 ESF CSU
Single-Port T1 Extended Super Frame (ESF) CSU Applications: Used in applications requiring FT1/T1 circuit termination with drop-and-insert capabilities via RJ-48C port. SNMP/Telnet management through the 8100A Site Controller.

APS Application Modules
 | 1557 APS card switches on selectable error events and is T1.403, TR54016, and AT&T 54017 compatible. Configuration guide included. Manuals shipped upon request only. |
| APS dual LIU card converts two DSX level signals to line levels with protection. Designed as a companion product to the 1557 APS to allow the 1557 to drive two facility lines. |
| 1250 Alarm/Power distribution card. Interfaces two -48 VDC external sources to the APS Chassis. This card is furnished standard with the APS chassis. It provides a Chassis Alarm indication whenever any of the installed cards is in an alarm state and also provides switches for Chassis Addresses. |
| 1558A Standalone APS unit provides Automatic Protection Switching and T1 performance monitoring for a single APS application. Switching from the active line to the standby line is determined by user programmable alarm thresholds. The DTE port may be configured for D4 or ESF Framing and AMI or B8ZS coding. Dual ESF CSU functionality. -20 to -56VDC. Ships with AC/DC wall transformer, 19" rack mount hardware, PC Local Access Software, Pc to 1558 data cable, and three 10 ft. Rj48 modular T1 cables. |
| 1558D Standalone APS unit provides Automatic Protection Switching and T1 performance monitoring for a single APS application. Switching from the active line to the standby line is determined by user programmable alarm thresholds. Integral ESF DSU/CSU. Ships with AC/DC wall transformer, 19" rack mount hardware, PC Local Access Software, PC to 1558 data cable, and three 10 ft RJ48 modular T1 cables. |
