Canadian Limitations Notice{xe "Canadian Limitations Notice"}
Notice: The ringer equivalence number (REN) assigned to each terminal device
provides an indication of the maximum number of terminals allowed to be connected
to a telephone interface. The termination of a interface may consist of any
combination of devices subject only to the requirement that the sum of the ringer
equivalence numbers of all the devices does not exceed 5.
Notice: The Industry Canada label identifies certificated equipment. This
certification means that the equipment meets certain telecommunications network
protective, operational and safety requirements. Industry Canada does not
guarantee the equipment will operate to the user’s satisfaction.
Before installing this equipment, users should ensure that it is permissible to be con-
nected to the facilities of the local telecommunications company. The equipment

nance facility designated by the supplier. Any repairs or alterations made by the
user to this equipment, or equipment malfunctions, may give the telecommunications
company cause to request the user to disconnect the equipment.
Users should ensure for their own protection that the electrical ground connections
of the power utility, telephone lines and internal metallic water pipe system, if
present, are connected together. This precaution may be particularly important in
rural areas.
Caution: Users should not attempt to make such connections themselves, but should
contact the appropriate electric inspection authority, or electrician, as
appropriate.

Introduction
The Multi-Tech MT5634HD8 is a high speed, high density modem card for the
CommPlete Communications Server. Each MT5634HD8 card contains eight inte-
grated 56Kflex modems. Each modem on the MT5634HD8 card can be configured
independently of the others via RASexpress Software or the CommPlete
Communications Server’s MR9600 controller, which can support and control up to 12
modem cards per rack. Users dial into the MT5634HD8’s modems through a T1
daughter card on the RASCard that controls the segment. There are no external
connectors.
Three MT5634HD8 cards must be installed per T1 segment. With eight modems per
card, the CommPlete Communications Server can support up to 24 simultaneous data
lines per segment, or 96 per CommPlete Communications Server
The MT5634HD8 operates as an enhanced ITU-T V.34 dial-up modem with a maxi-
mum K56flex speeds, and is a fully digital K56flex server. As such, it includes the
advanced features of Multi-Tech standalone modems such as the popular
MultiModemZDXb.
The MT5634HD8 is registered by the {xe "FCC regulations"}FCC for direct
connection to the public telephone networks. No Data Access Arrangements ({xe
"DAA"}DAAs) are required.
The MT5634HD8 is fully compatible with the standard AT command set, and is
therefore compatible with all popular communications software packages.
This user guide will help you to install, configure, test, and use the MT5634HD8.

LED Indicators
The MT5634HD8 has 16 LED indicators{XE "indicators" }{ XE "LED indicators" }on
the front panel, two for each modem:
CD Carrier Detect. {xe "CD signal"}The CD LED lights when the modem detects
a valid carrier signal.
OH Off Hook/Out of Service. The OH LED lights when the modem is off hook,
which occurs when the modem is dialing, online, or answering a call. The LED
flashes when the modem is in the {xe "busy-out state"}busy-out or {xe "out-of-
service state (OOS)"}out-of-service state.
Power Supplies{xe "power"}
DC voltages are supplied to all modems in the CC9600 rack through two PS9600
universal input switching power supplies designed for conventional 115 or 230 VAC
input. The power supplies are designed for redundant, fail-safe operation. If one
should fail, the other can supply the power requirements of the entire CommPlete
Communications Server. Each PS9600 power supply has one LED indicator that
indicates the presence of all supply voltages.
