INSTALLATION INTER-TEL PRACTICES Issue 2, May 1990 GMX-48 INSTALLATION & MAINTENANCE D. SECONDARY VOICE PATH INSTALLATION 4.13 If desired, the system can be configured to al- low 24-line keyset users to receive off-hook voice an- nounce (OHVA) calls and/or to use the simultaneous voice/data communication feature. To accomplish this, the keyset is installed on an odd-numbered sta- tion circuit (e.g., 1.1, 1.3, 1.5, etc.). Then, the follow- ing even-numbered circuit (1.2, 1.4, 1.6, etc.) is...

INTER-TEL PRACTICES GMX-48 INSTALLATION & MAINTENANCE ‘.. INSTALLATION Issue 2, May 1990 5. 5.1 TERMINATING C.O. LINES AT THE MDF The installation procedure used to terminate C.O. lines at the MDF is dependent on the type of termination used by the telephone company and how close it is to the MDF. The C.O. lines may be termi- nated on RJ-type jacks or on an RJ-type block. 5.2 Follow one of the three C.O. termination meth- ods (A, B, or C) outlined on the following pages. IMPORTANT NOTES:...
