Chapter Title

Customer-Supplied Equipment

The following customer-supplied equipment is required to complete a data communications system using either the Model 3810 or Model 3820 modem:

•A DTE with an available EIA-232-D serial port.

•A standard EIA-232-D male-to-female cable with a male DB-25-S connector at one end to attach to the modem.

•One of the following modular dial or leased network interfaces:

—RJ11C for dial permissive applications

—An 8-position to 6-position crossover cable for JM8 leased-line applications only

The following customer-supplied equipment is required for the installation of a Model 3811 modem:

•A COMSPHERE 3000 Series Carrier.

•A male-to-female 50-pin mass termination cable. One Network Interface Module (NIM) for modems installed in Slots 1–8 and one NIM for modems installed in Slots 9–16 (required for dial-line applications).

•One of the following modular or 50-pin dial or leased network interfaces:

—RJ11C for single line dial permissive applications

—RJ21X for multiple line dial permissive applications

—66 punchdown block or other demarcation device

•One 6-position to 6-position modular cord (required for network management applications).

•A Shared Diagnostic Unit (SDU) (required for network management applications).

If the modem is to be managed by a network management system, a Shared Diagnostic Unit (SDU) must be supplied and properly connected to the network management controller. For proper network management connection to the SDU, refer to the COMSPHERE

6700 Series Network Management System User’s Guide.

For installation of the 3000 Series Carrier into a cabinet, refer to the COMSPHERE 3000 Series Carrier, Installation Manual.

Model 3810 or Model 3820 Modem Installation

Before installing your standalone modem, make sure your installation site is clean and well-ventilated. Allow space around the modem for installing cables and telephone cords, and make sure the modem is located within reach of the ac power outlet. The distance between your modem and DTE should be minimized if DTE data rates exceed 19,200 bps. Also, low capacitance cables may be necessary for speeds greater than 19,200 bps or distances greater than 50 feet.

The rear panel of both the Model 3810 and Model 3820 modems have the following switches and connectors (see Figures 2-2 and 2-3):

•An ON/Off power switch.

•A 5-pin DIN type power receptacle for ac power transformer.

•An 8-pin modular keyed jack for 4-wire/2-wire leased lines or external telephone set on the Model 3810. On the Model 3820, this jack is for external telephone set use only.

•An 8-pin modular keyed jack for dial (Public Switched Telephone Network, or PSTN) lines on the Model 3810. On the Model 3820, this jack is for dial or 2-wire leased lines.

•A 4-pin modular jack for Network Management System (NMS) connection.

•A 25-pin DB-25-S receptacle for DTE interface.

Figure 2-2 and Figure 2-3 show how Model 3810 and Model 3820 modems are connected to certain TELCO jack types using the supplied cables. For other TELCO connections, refer to Appendix E.
