Cable Basics
This guide provides all the information you need to find a specific cable for your
Nortel Networks router hardware platform. This chapter explains:
• What you need to know
• How to use this guide
-- How to find cables by category
-- How to find cables by order number or description
• Some basics about cable connectors, including:
-- Connector terminology
-- Basic connector types
• How to build your own cables
If you want to build a cable to meet special requirements, this guide also provides
pinout information and references to the appropriate documents for industry
specification, standards, or recommendations. Recommended documents typically
contain technical information to help you determine your requirements for cable
installation path, cable type, maximum cable length, and so on.

Before You Begin
To ensure that you order, make, or use the appropriate cable for your router
hardware platform, first answer the following questions:
• What is the connection category, order number, or physical description of the
cable I want to find?
• What type of physical interface am I connecting to, and what type of cable
connector (plug or receptacle) do I need to make this connection?
• What type of device do I want to connect to the router hardware platform’s
physical interface? For example, do you want to connect a modem or a
console to the router hardware platform? Each function requires a different
cable, even though you connect to the same physical interface on the router
hardware platform.
• What version of software is my router hardware platform using? For example,
newer features such as dial-up services may require special cable pin
configurations to interoperate with earlier versions of Nortel Networks
software.
How to Use This Guide
You can find the Nortel Networks cable you want by:
• Cable connection category
• Cable order number or description
Note: Determining the connector type you need can significantly decrease the
time it takes to locate the appropriate cable. For example, if you want to
connect to a 44-position synchronous interface, look only for synchronous
cables with 44-pin plugs.

Finding Cables by Category
This guide organizes Nortel Networks cables into seven connection categories.
Table 1-1 shows the chapter that contains each category.
After determining the connection category and type of connector that you need, go
to the appropriate chapter. The table at the beginning of each chapter provides
additional information about each cable in that category.

Cable Connector Basics
Before using this guide, you should be familiar with its terminology and the
connector types Nortel Networks provides.
Connector Terminology
This guide uses several terms to describe generically the various types of
connectors and their physical/electrical attributes. Table 1-3 lists these terms and
their definitions.
7948 50-pin to 15-pin V.35 cable adapter 8-14
77850 25-pin D-sub plug to RS-232-C modem plug (for BLN/BCN console/modem
interface to dial modem connection) 2-7
Table 1-3. Connector Terms
Term Description
Pins These are the short, rigid, lead wires protruding from a plug-type connector. The pins
of a plug connector penetrate and make electrical contact with counterpart sockets,
or holes, in a receptacle-type connector.
Sockets These are the holes in a receptacle-type connector. Each hole:
• Accepts one counterpart pin of a plug-type connector
• Completes an electrical connection to its counterpart pin
Plug This type of connector provides a number of pins and attaches to a receptacle-type
connector.
Receptacle This type of connector provides a number of sockets, or holes, that accept the pins of
a plug-type connector.
Physical
interface This is a plug- or receptacle-type connector located on the router hardware platform
or on a device such as an Ethernet transceiver. The physical interface accepts an
appropriate (counterpart) cable connector.
Termination This is the connector at one end of a cable; a termination can be either a plug- or
receptacle-type connector.

Connector Types
Nortel Networks provides the following connector types:
• Attachment unit interface (AUI): A 15-pin D-type connector that connects
equipment to the Ethernet network through a transceiver
• CCITT series (V.28, V.35): CCITT-recommended V.10 (unbalanced) and V.11
(balanced) standard connectors
• Data terminal equipment (DTE) to data communication equipment (DCE)
interface (X.21): CCITT-recommended DTE to DCE synchronous/public
switched network connector
• Fiber channel (FC): Threaded, straight-tip, coaxial or fiber optic connectors
• Fixed shroud duplex (FSD): Jack-type, dual fiber optic connector for use in
FDDI networks
• Media access unit/multistation access unit (MAU): LAN wiring concentrator
used in token ring networks
• Recommended standard (RS-232-C, RS-449/RS-422): EIA standard
connectors for use with DTE and DCE devices
• Registered jack series (RJ-45; RJ-48): 8-position, FCC-registered data plugs
• Subscriber connector (SC) duplex: Jack-type, dual fiber optic connector for
use in FDDI networks
• Spade terminals: Flat, U-shaped connectors typically used for T-carrier line
connection
• Straight-tip (ST): Bayonet coaxial or fiber optic connectors
Figure 1-1 shows a sample of connectors in cable assemblies for Nortel Networks
router hardware platforms.
Note: Many types of fiber optic connectors include a dust cover. (Dust
obstructs or attenuates optical signals entering or leaving the cable through the
connector.) Be careful not to lose the dust cover when you attach a fiber optic
cable connector to its counterpart connector. Replace dust covers when you
detach a fiber optic cable from any local device.

Building Your Own Cables
Cables that you build must comply with standard cable specifications and network
requirements. Cable length, cable type, cable and connector attenuation, and other
factors affect the overall performance and reliability of your network.
For example, using a cable length longer than that recommended in industry
standards or interface specifications, or using a cable type that is unsuitable,
considering the cable environment (temperature, electrical noise, radio-frequency
[RF] emissions, and other factors) may degrade network performance and
reliability.
For additional information about maximum cable length and other factors, consult
the appropriate EIA, IEEE, CCITT, or ISO specification, standard, or
recommendation. Some examples include:
• IEEE 802.3 10BASE-T Specification (10 Mb/s CSMA/CD over twisted pair)
• IEEE 802.5 Specification (token ring)
• X3T9.5 Single-Mode Fiber PMD Specification (FDDI)
• EIA RS-449/RS-422A Standard
• EIA RS-232-C Standard
• CCITT V.10/V.11/V.28/V.35 Recommendations
• CCITT X.21 Recommendation
See also the manufacturer’s specifications for any cables or connectors you want
to use. Specifications for attenuation per unit length of cable, and for connector
insertion loss, are useful in helping you to determine the maximum amount of
signal loss (and, therefore, the maximum distance) allowable between two directly
connected network devices.
The physical interface on each device (for example, the connector on an Ethernet
link module in a Nortel Networks router hardware platform) determines which
industry specification, standard, or recommendation you need to consult for
guidelines on how to customize your cables.
To assist you in determining which industry document you need to consult, the
description for each cable in this guide includes an “Industry Interface Type”
description.

The following sections include:
• Cable illustrations with the Nortel Networks connector on the left and the
remote connector on the right
• Cable length information
If you want to build a cable, and you want to determine the maximum cable
length appropriate for that interconnection requirement, you should:
-- Identify in this chapter a cable that satisfies your interconnection
requirement (with the exception of total cable length).
-- Consult the networking industry specification, standard, or
recommendation designated in the “Industry Interface Type” entry for that
cable (located immediately following the cable pinout diagram).
• Pinouts for each connector and all associated signals
• Internal wire connections for each termination (when applicable)
For example, the console port to ASCII terminal cable (Order No. 7525) lists
internal wire connections such as “Pin 6 > 20” in the Remote Termination
column. This indicates that you must connect pin 6 to pin 20 inside the remote
termination.
• Grounding arrangements that isolate the chassis from the DC ground within
the cable (when applicable)

HSSI Crossover (Order No. 7832)
Industry Interface Type: High-Speed Serial Interface (HSSI)
This cable is intended solely for test environments; you cannot use it in production
applications.Within such test environments, this cable provides a proprietary,
nonstandard, back-to-back connection of Nortel Networks router hardware
platforms (through their HSSI ports) without intervening digital service unit
(DSU) equipment.
When using the Nortel Networks HSSI crossover cable, you must set the HSSI
interfaces to clock internally. The data rate under internal clocking conditions
must not exceed 25 megabits per second (Mb/s). (HSSI operation in a production
environment allows for a DSU configuration from 300 Kb/s to 52 Mb/s.)
For additional information about enabling internal clocking, refer to Using
Technician Interface Software (router software) or Administration Guide
(BayStream™ software).

If you need to order additional cables, contact the Nortel Networks Technical
Solutions Center in your area. (See “How to Get Help” in the preface.)
The following sections include:
• Cable illustrations with the Nortel Networks connector on the left and the
remote connector on the right
• Cable length information
If you want to build a cable, and you want to determine the maximum cable
length appropriate for each of your interconnection requirements, you should:
-- Identify in this chapter a cable that satisfies your wiring requirement (with
the exception of total cable length).
-- Consult the networking industry specification, standard, or
recommendation designated in the “Industry Interface Type” entry for that
cable (located immediately following the cable pinout diagram).
• Pinouts for each connector and all associated signals
• Wire jumper identification for each connector (when applicable)
For example, the Sync to V.35 cable (Order No. 7215) lists internal wire
connections (Pin 1 > 7) in the Nortel Networks Termination column. This
indicates that you must connect pin 1 to pin 7 inside the Nortel Networks
connector.
• Grounding arrangements that isolate the chassis from the DC ground within
the cable

If you need to order additional cables, contact the Nortel Networks Technical
Solutions Center in your area. (See “How to Get Help” in the Preface.)
The following sections include:
• Illustrations for each cable with the Nortel Networks connector on the left and
the remote connector on the right
• Cable length information
If you want to build a cable, and you want to determine the maximum cable
length appropriate for each of your interconnection requirements, you should:
-- Identify in this chapter a cable that satisfies your wiring requirement (with
the exception of total cable length).
-- Consult the networking industry specification, standard, or
recommendation designated in the “Industry Interface Type” entry for that
cable (located immediately following the cable pinout diagram).
• Pinouts for each connector and all associated signals
• Wire jumper identification for either connector (when applicable)
For example, the 15-pin D-sub to RS-422 cable (Order No. 7116) lists internal
wire connections (Pin 7 > 12; Pin 25 > 30) in the Remote Termination column.
This indicates that you must connect pin 7 to pin 12 and pin 25 to pin 30
inside the remote connector.
• Grounding arrangements that isolate the chassis from the DC ground within
the cable
