The 700A DS1 CPE Loopback Jack (T1 Only) (107988867) is a refurbished telecommunications testing component designed for compatible Avaya DS1/T1 installations. Identified by apparatus code 700A and comcode 107988867, the loopback jack allows a technician to test the DS1 span between the telephone system and the network interface point. It is particularly important in installations where DC power is present at the interface to the Integrated Channel Service Unit (ICSU).
700A DS1 CPE Loopback Jack (T1 Only) Features
The 700A DS1 CPE Loopback Jack(107988867) provides a convenient method for testing and maintaining compatible DS1 spans. When DC power appears at the interface to the ICSU, the loopback jack isolates the ICSU from the DC power while properly looping the DC span power. This allows technicians to perform appropriate testing while maintaining the required isolation between components.
- Designed specifically for compatible DS1/T1 applications
- Apparatus code 700A
- Comcode 107988867
- Allows testing of the DS1 span between the system and network interface point
- Isolates the ICSU when DC power appears at the interface
- Properly loops the DC span power
- Supports compatible TN767E or later DS1 circuit packs
- Supports compatible TN464F or later DS1 circuit packs
- Supports G3V3 EDI Release 3 or later software
Requirements and Compatibility
The 700A DS1 CPE Loopback Jack (T1 Only) operates with any vintage of TN767E or later and TN464F or later DS1 circuit packs when used with compatible G3V3 EDI Release 3 or later software.
The 700A operates with the 120A2 or later Integrated Channel Service Unit (ICSU) only. It is not intended for use with 31xx Series CSUs, other external CSUs, or earlier CSU equipment. Because this is a specialized telecommunications component, verify the installed circuit pack, ICSU, and system configuration before ordering.
DS1/T1 Testing and Replacement Equipment
For organizations maintaining compatible Avaya DS1/T1 communications equipment, the 700A Loopback Jack can be used as a replacement component or kept available for system maintenance and testing requirements. Its ability to isolate the ICSU and provide the required loopback functionality makes it an important component in supported DS1 installations.
