The ACCULINK front panels include an LCD display and 7-button keypads composed of three functional and four directional keys.

They contain integral 2400-bps modems for remote access and alarm reporting.

The front-panel LEDs are labeled and colored differently from the ESF T1 CSU.

The NETWORK connectors on the rear of the ACCULINK models are 8-pin modular jacks (RJ48C) instead of male 15-pin D-connectors. Cables are shipped with the units for the CSU-to-Smart Jack connection.

■There are no DIP switch options. All options are set via software commands. Access the options in the following ways:

—Locally, from the front panel

—Remotely, using the integral 2400-bps modem. The front panel of a local ACCULINK, in Passthrough mode, can access and option a remote CSU

—Locally and remotely, through the COMPORT connector on the rear and a PC loaded with a Windows software package (available at an extra charge from Paradyne)

NOTE:

If you are upgrading to Release 6.0 or 6.1, make sure the CSU is programmed for PRI signalling at either end of a PRI tandem trunk. You may have an existing setting for T1 or robbed-bit signaling rather than PRI signaling. If the CSU is not set for PRI signalling, you will get an error message, “PRI D-channel inoperative.”

The ACCULINK CSUs come equipped with two factory-set option configurations: Factory 1 (Fact 1) and Factory 2 (Fact 2). They leave the factory set at Fact 1. Two of the default parameters in Fact 1 are ESF/B8ZS. In the Fact 2 setting, two of the default parameters are D4/AMI.
