Preface
The DEC CT1controller 100
The DEC CT1controller 100 is a TURBOchannel option that provides
a single Channelized T1 (CT1) port. This port is connected to a public
telecommunications network through an appropriate Channel Service Unit
(CSU).
The DEC CT1controller 100 can provide up to 24 connections of 64 Kbits/s over
a single T1 line. That line has a maximum data rate of 1.536 Mbits/s.
This booklet contains information to help you install the option successfully,
and to attach the necessary communications cable. It also contains information
that can help diagnose problems if they occur.
Structure of this Booklet
This booklet covers the following topics:

PTT Information
Federal Communications Commission
The following instructions are provided to ensure compliance with the Federal
Communications Commission (FCC) Rules, Part 68.
1. This device must only be connected to the T1 network behind an
FCC Part 68 registered channel service unit. Direct connection
is not allowed. The registered CSU will provide the necessary isolation
when connected between this device and the T1 network.
2. Before connecting your unit, you must inform the telephone company of the
following information:
Port ID REN/SOC FIC
DEC CT1controller 100 6.0P 04DU9-BN,
04DU9-IKN
04DU9-DN,
04DU9-ISN
3. If the unit appears to be malfunctioning, it should be disconnected from the
telephone lines until you learn if your equipment or the telephone line is
the source of the trouble. If your equipment needs repair, it should not be
reconnected until it is repaired
4. If the telephone company finds this equipment is exceeding tolerable

Canadian Department of Communications Notice
NOTICE: The Canadian Department of Communications label identifies
certified equipment. This certification means that the equipment meets certain
telecommunications network protective, operational, and safety requirements.
The Department 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 connected to the facilities of the local telecommunications company. The
equipment must also be installed using an acceptable method of connection. In
some cases, the company’s inside wiring associated with a single line individual
service may be extended by means of a certified assembly (telephone extension
cord). The customer should be aware that compliance with the above conditions
may not prevent degradation of service in some situations.
Repairs to certified equipment should be made by an authorized Canadian
maintenance 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 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.
The Load Number (LN) assigned to each terminal device denotes the
percentage of the total load to be connected to a telephone loop which is used
by the device, to prevent overloading. The termination on a loop may consist of
any combination of devices subject only to the requirement that the total of the
Load Numbers of all the devices does not exceed 100.

Problem Solving
3.1 Overview
If problems arise in the use of the DEC CT1controller 100 they can occur at
either of the following times:
• Power up
• During operation
This chapter shows how to diagnose each type of problem. Use this chapter in
conjunction with the hardware documentation for the host system.
Problem Solving 3–1

3.2 Power Up
3.2.1 Powerup Actions
When power is applied to the DEC CT1controller 100, it carries out a series
of self-tests. The tests take approximately 1 minute to complete, and their
progress is shown by the LEDs on the front panel:
LED Use
OK (green) Lights briefly between each test and is permanently displayed when the
tests have completed successfully.
RA (red) Lights if any test fails.
YA (yellow) Lights while each test is in progress.
LB (green) Not used during the powerup tests.
3.2.2 Powerup Problems
If the RA LED lights at power up, the DEC CT1controller 100 is faulty.
Replace the unit, following the instructions in the documentation for the host
system.
3.3 Operational Problems
The following table shows the LED displays that can occur during operation.
LED State Meaning Action to Take
OK (green) On
Off Normal operation Software has suspended None Refer to the host software
documentation
RA (red) On Local detection of line failure Refer to the host software
documentation
YA (yellow) On Remote indication of line failure Refer to the host software
documentation
LB (green) On Loopback tests in progress Refer to the host software
documentation
3.4 Console Messages
Some host systems have a console that logs messages from the system
components. Replace the DEC CT1controller 100 if it generates any of the
following messages on the system console.
