Installing and Connecting the Hardware

Connecting to a Modem for Remote Management

Before connecting the HotWire 8600 DSLAM to a dial up modem, configure the modem with the following settings:

￿Set the modem for auto answer. For example, ATS0=1.

￿Turn off character echo. For example, ATE0.

￿Enable result codes in originate mode only. For example, ATQ2.

￿Set the modem to ignore Data Terminal Ready (DTR). For example, AT&D0.

"Procedure

To connect the HotWire 8600 DSLAM chassis to a dial up modem:

1.Connect an 8-pin modular plug-ended serial cable into the MANAGEMENT SERIAL port of the HotWire 8600.

2.Dress the serial cable under the 8600 chassis, to the left and behind the support foot.

3.Plug the other end of the cable into your modem's serial port using a DB25 (RS-232 male) adapter, supplied with the MCC card, and a Null Modem adapter.

Refer to Appendix B, Pinouts, for pin assignments.
