ADTRAN E220 HFAC HDSL2 Installation, Electrical cable compliance, Configuration, Shelf Address

The HFAC supports the HTU-Cs / H2TU-Cs listed below.

¥	1245001L2	¥	1246001L2
¥	1245001L9	¥	1221001L2
¥	1245011L1

The differences in functionality when working with list-specific HTU-Cs / H2TU-Cs or HREs / H2Rs, if any, are called out in this practice. Also, the HFAC has necessary interface software for communications with the HCOT-CTL (ADTRAN p/n: 1240009L1, 1244051L1, 1221051L1). See appropriate HCOT practices for installation and maintenance information.

The HFAC collects and presents performance information for each circuit deployed in the shelf. It also allows control of all provisioning information for each circuit. The unit can also be configured to provide advanced alarm processing features.

Configuration

Operation of the HFAC is influenced by three sets of configuration option switches (see Figures 2 and 3).

Shelf Address

Two rotary switches (U38 and U39) are provided to program the shelfÕs address. In a system where several shelves are under the common control of one ADTRAN E220 HCOT-CTL System Controller, each individual shelf must be programmed with a unique shelf address. Addresses range from 00 to 99. In a system that does not utilize the HCOT-CTL System Controller, the shelf address is not used. To program
