CHAPTER 5. AUXILIARY EQUIPMENT INSTALLATION
Installing AUDIX Interface—R1V3 Only
Requirements
The interface between the switch and the AUDIX/Adjunct or AUDIX
terminal is through PDMs. AUDIX terminals can also be connected
through the cross-connect field to the AUDIX. The large AUDIX is not
supported by System 75 or 75 XE.
●
●
System 75, Version 3 uses interface 1 (TN716), interface 2
(TN738), and interface 3 (TN719) as the required control circuit
packs.
System 75, XE uses the processor interface (TN765) as the
required control circuit pack.
Connections between the AUDIX interface and the switch are covered
in the section for installing PDMs (Figures 5-21 and 5-22). The AUDIX
requires up to 16 analog circuit pack ports from the switch to be
connected through the cross-connect field to the AUDIX. Refer to Table
3-H for port circuit pin numbers.
Information for connecting the PDMs to the AUDIX and setting the PDM
option switches is contained in the AUDIX-M—Installation Service Manual,
585-300-103.
Installing CMS Interface—R1V3 Only
Requirements
The interface between the switch and the CMS is through PDMs.
●
●
System 75, Version 3 uses interface 1 (TN716), interface 2
(TN738), and interface 3 (TN719) as the required control circuit
packs.
System 75 XE uses the processor interface (TN765) as the
required control circuit pack.
Connections between the CMS interface and the switch is covered in
the section for installing PDMs (Figures 5-21 and 5-22).
