 Wideband 3190 shelves only

Digital Data Service (DDS) latching loopback

Network Management and Administration (NMA) interface

Metallic Test Access (MTA)

Dual DSX-1 port option

The H2TU-C has two unique features, Metallic Test Access and Dual DS1 port options, which are not provided 
in standard ADC line units with 3192 mechanics. These features require additional access pins which are provided 
by a special card-edge connector, shown in 

. Only the HMS-358 set of shelves can 

accommodate this special connector. 

HiGain HDSL2 systems provide a cost-effective, easy-to-deploy method for delivering T1 High Capacity Digital 
Service (HCDS) over a single copper pair. HiGain HDSL2 systems support a multitude of network connections 
and system models.

The service is deployed over one unconditioned, non-loaded copper pair.

Conventional, inline DS1 repeaters are no longer required.

Cable pair conditioning, pair separation and bridged tap removal are not required.

Each loop has no more than 35 dB of loss at 196 kHz, with driving and terminating impedances of 135

Ω

. In 

general, HiGain HDSL2 systems:

Operate effectively in the same cable binder group with other HDSL2 lines, HDSL, T1, ADSL, SDSL, POTS, 
DDS, and other transmission schemes.

Can be used with customers requiring DS1 service on a temporary or permanent basis.

Provide a means of quickly deploying service in advance of fiber-optic transmission systems.
