Installation

The H192 requires 2U (3.5 inches) of rack

supplied with mounting brackets and hardware
to allow installation in a 19 inch or 23 inch rack.
The H192 must only be installed in restricted
access locations by trained personnel.

Grounding

To comply with the Network Equipment Building Systems (NEBS)
requirements, a suitable ground must be provided. The H192 can
be grounded to the rack through a grounding screw on the right
side. Grounding lugs are provided on the rear of the H192 to
provide an accessible termination point for cable shield/25
grounds. On the front, pins 25 & 50 (the 25

Cabling Overview

The H192 Splitter Shelf cabling configurations will vary depending on installation locations and the number of lines
supported by the DSLAM. The physical connectors are the standard 50-pin Amphenol-type female connectors.
Each Splitter card uses 24 of the available 25 pairs on each 50-pin connector.
The DSL Interface
connectors are front
mounted with the LINE
and POTS Interface
connectors mounted
on the rear of the shelf.

Each cable head should be secured with a tie wrap and the cable head screw.

Installation of Cards

The H192 has two types of splitter cards available: North American ADSL (NA-2820) &
North American VDSL2 (NA-2820V). Up to 8 cards can be installed in each shelf. It is
not recommended to mix the two card types in a single shelf.
To install, align the space between the two PCBs, on the splitter card, with the card
guides on the shelf. When the card’s gold fingers reaches the rear connectors, ensure
the inserters/ejector mates with the rectangular opening on the bottom of the shelf.

Connector Pinouts

As viewed from the front of the shelf:

• Using 24 pair telephone cables, 24 high speed xDSL signals to and from the DSLAM enter the H192 splitter
shelf using the DSL connector on each face plate.
