1.0 Introduction
The Model 922-DSLH is a combined (hybrid) Digital Subscriber Line (DSL) modem, optical modem, Ethernet
switch, and serial server. As a modem, it offers redundant long range communications over copper and up to
200 km of optical fiber. With the on-board Ethernet switch and a configurable serial server, this highly integrated
and multi-functional gateway card incorporates well into Subsea Electronics Modules (SEM) and other types of
subsea nodes, often replacing several cards with one board to save space and minimize sparing costs. An
optional interface module enables the DSL to run over existing AC power lines.
Supported communication formats include SIIS Level 3 Ethernet and serial protocols such as RS-232, RS-485
and RS-422 (IWIS). The card also performs format conversion, such as Modbus RTU (serial) to Modbus TCP
(Ethernet). System integrators can easily adapt legacy serial sensor interfaces to Ethernet based systems with
both fiber-optic and high-speed copper communication links. Conversely, Ethernet traffic can now be extended
over existing low-speed serial communication links using PPP (Point to Point Protocol).
The Model 922 software provides advanced diagnostics via Modbus TCP for real-time health monitoring of the
system as well as easy configuration of all interfaces and modes of operation.

1.1 Safety Precautions
The following safety precautions should be observed before using this product.
This product is intended for use by qualified personnel who recognize shock hazards and
are familiar with safety precautions required to avoid possible injury. Do not make module
connections unless qualified to do so.
Before connecting this product to the power source, verify that the output voltage is within
the specifications of the product’s power supply.
Do not attempt to modify or repair any circuit unless recommended by the manufacturer.
Protect the power cable from being walked on or pinched by items placed or against
them.
Always unplug the power cable at the plug, do not pull on the cord itself.
Do not block any ventilation openings.
Do not look into the end of a fiber when it is plugged into a transceiver or active fiber,
especially when using a magnifying instrument, such as a fiber microscope.
Handle optical fiber with extreme care. Glass fiber is subject to breakage if mishandled.

3.0 Architecture Overview
The Model 922-DSLH provides access to one (1) DSL (with or without power line interface board) channel, two
(2) RS-232/422/485 isolated serial data channels, two (2) 10/100Base-T(X) Ethernet ports (CU1-2) via a
backplane and one (1) SFP (100Base-FX or 10/100Base-T(X)) as shown in the figure below.
The 922-DSLH PCB has a Eurocard form factor with two daughter cards. One daughter card provides the DSL
function and the other daughter card (located at the front of the card) provides a power line interface. The copper
Ethernet ports CU1, CU2 and serial channels 1-2 are accessed via the 96-pin DIN backplane connector, and
the SFP port (located at the front of the card) is accessed via an SFP transceiver.
