ARN Expansion Modules Safety Status

ARN expansion modules are upgrade options that provide an additional synchronous interface. These options can be installed in any ARN model.

Table D-4 lists the safety status of the interconnection point (COM3, COM4, COM5, COM6, COM7, COM8, and COM9) provided by each of the expansion modules (Order Nos. CV0004011, CV0004012, CV0004013, CV0004014, CV0004015, CV0004026, and CV0004027) to the connection of other equipment.

Synchronous Cabling Requirements

Refer to Figures D-1 through D-6 and Tables D-5 through D-10 for serial interface cabling information.

Note the following compliance requirements:

•V.28 compliance requires an Order No. 7837 or 7934 cable.

•V.35 compliance requires an Order No. 7220 or 7932 cable

•X.21 compliance requires an Order No. 7224 or 7936 cable.
