OVERVIEW

The PairGain®HiGain®Model HLU-319 List 5C is the Central Office (CO)

side of a repeaterless T1 transmission system.It is used in conjunction with a

HiGain Remote Unit (HRU) or HiGain Doubler Unit(s) (HDU) to provide a

complete HiGain High-bit-rate Digital Subscriber Line (HDSL) system.

The CSA includes loops up to 12,000 feet (3658m) of 24 AWG or 9,000 feet

(2743m)of 26AWG, including bridged taps. The HiGain system uses HDSL

transmission technology as recommended by Bellcore TA-TSY-001210.The

HiGain system complies with GR-63-CORE, TR-TSY-000499, and

GR-1089-CORE.

The HLU-319 List 5C supports Digital Data Service (DDS) loopback

commands and has special features as described in the technical practice for

the unit (see “Documentation” on page 12).

•PairGain HMS-317 (28-slot, 23-inch shelf)

•PairGain HMS-318 (22-slot, 19-inch shelf)

•PairGain HHS-319 (3-slot, 19-inch horizontal shelf)

•PairGain HMS-308 (8-slot remote enclosure)

•Charles Ind. #3192 (28-slot connectorized)

•Charles Ind. #3192-9F Alarm Card

•Charles Ind. #3192-WR (28-slot wire wrap)

•Charles Ind. #343-00 (12-slot to 14-slot wire wrap)

•Charles Ind. #319-02 (22-slot connectorized)

•Charles Ind. #319-04 (22-slot wire wrap)

•Charles Ind. #340-00 (9-slot to 11-slot wire wrap)

HLU-319 List 5C April 30, 1999 6

PROVISIONING

The HLU-319 List 5C contains Non-volatile Random Access Memory

(NVRAM) which stores the system option settings. System settings are

retained if shelf power is lost or if the HLU-319 is unplugged. [No Dual

In-line Package (DIP) switch or jumper settings are required.]

NAVIGATION KEYS

Table 3 lists keys you can use on the maintenance terminal to navigate within

the Maintenance Terminal screens.

The maintenance terminal screens cannot be accessed

through the HLU-319 List 5C, as this model does not provide

a craft port. View these maintenance terminal screens

through the HiGain Management Unit (HMU) or OS port

located on the rear of the HiGain shelf or WBS-3190.

If using the Microsoft Windows terminal emulation program,
