3600 Hubbing Device Installation Instructions

Document Number 3610-A2-GZ45-10

March 1996

Overview

This document describes the pin assignments and procedure for installing the 3600 Hubbing Device.

•

The 3600 Hubbing Device is required to daisy chain a Model 3610 Data Service Unit (DSU) onto a Network Management System (NMS) control channel (CC) or diagnostic channel (DC).

•

The hubbing device plugs into a modular jack located on the rear of the DSU and provides two

8-pin modular jacks for DC/CC connections.

Prior to installing a 3600 Hubbing Device, check the hubbing device for damage. If there are signs of damage, report this immediately to your shipping representative and your AT&T Paradyne representative.

WARNING

This equipment has been tested and found to comply with the limits for a

Class A digital device, pursuant to

Part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case, the user will be required to correct the interference at his own expense.

The authority to operate this equipment is conditioned by the requirement that no modifications will be made to the equipment unless the changes or modifications are expressly approved by

AT&T Paradyne.

TO USERS OF DIGITAL APPARATUS IN

CANADA: The digital apparatus does not exceed the Class A limits for radio noise emissions from digital apparatus set out in the radio interference regulations of the Canadian Department of

Communications.

8-Pin Modular Jacks

Use the 8-pin modular jacks to connect the DSU to the

Network Management System, another 3600 Hubbing

Device, or a 3400 Hubbing Device. One jack supports CC in and DC out. The other jack supports CC out and DC in.

Tables 2 and 3 list the pin numbers and signal names.

NOTE

The pin numbers on both modular jacks are compatible with the 3400 Hubbing Device.

Therefore, no additional adapter is required when using the 3600

Hubbing Device and the 3400

Hubbing Device in the same configuration.

Installing the 3600 Hubbing

Device

NMS Network

Connection

NOTE

When installing 3600 DSUs and

3400 Series or DATAPHONE II modems on the same DC, install the DSU ahead (upstream) of the modems. This configuration prevents the DSU from losing contact if the modem loses power.

.

Procedure

To connect the 3600 Hubbing Device to the DSU:

1. Configure the DSU for either CC or DC operation using the Diagnostic Connection configuration option as described in the COMSPHERE 3600

Series Data Service Units, Models 3610 and 3611,

User’s Guide, Document number 3610-A2-GB46.

2. Plug the hubbing device’s 4-pin modular plug into the jack labeled CC/DC and located at the rear of the DSU.

3. Plug one end of the M6BJ cable into the hubbing device jack labeled CC IN/DC OUT.

4. Plug the opposite end of the M6BJ cable into the appropriate 6700 or 6800 Series NMS jack.
