Overview

This appendix lists the pin assignments for VF Telco, EIA-232-D, and EIA RS-366-A interfaces.

VF Connector Pin

Assignments

Tables E-1 and E-2 list the connector pin assignments for Model 3810 and Model 3820 modular jacks and the pin assignments for the Telco jacks. For 2-wire leased-line connections to a JM8 network interface, an 8-position to

6-position crossover cable (see Figure E-1) must be used according to the following FCC requirements:

‘‘The RJ series of jacks should not be used for connecting data equipment to nonswitched private line networks – specifically, the service equivalents of the

pre-divestiture Series 3002 (Category II, Tariff #260) service. There is a substantial difference in transmit levels permitted in the private line service and those permitted in the public switched network. The industry standard is now an 8-pin keyed modular jack known as the USOC JM8 (Bellcore Technical Reference: TR-EOP-000242, Issue 1, released May 1985.) When ordering the installation of the USOC JM8, specify the appropriate wiring options:

1.2- wire operations

2.4-wire operations w/o TEK leads

3.4-wire operations with TEK leads

TEK leads are for loopback purposes.

A 50-pin version is being considered for multiple line connections.”

Insert the 6-position plug into the LEASED jack of your modem. Insert the 8-position plug into the leased-line network interface.
