Electronic Hookswitch (EHS) Cables

For Avaya, Cisco, Polycom, Siemens, ShoreTel and other IP phone systems.
Electronic Hook Switch - communicates electronically with the phone, eliminating the need for a HL10 lifter.
Note that Savi EHS cables work only with the Savi Office Wireless headset system.
CS-xx EHS cables are designed for CS55, CS70N and CS351N/CS361N wireles headsets, and can not be used with the Savi Office. Cables are generally identified by a 2 digit code for Savi Office, and a 1-digit code for CS-xx. e.g. APC-40 for Cisco/Savi Office, and APC-4 for Cisco/CS-xx.
See the EHS-Compatibility Guide and Electronic Hook Switch Setup Guide for supported phone systems and hook-up information.

Refer to the EHS Cable Compatibility Guide for detailed connection and setting information
