Cabling Summary
Introduction
This appendix provides details on the cabling required to connect customer devices to an IGX node. In all cable references, the transmit direction is from the node, and receive is to the node.
Note 
EIA/TIA-232 and EIA/TIA-449 existed as recommended standards RS-232 and RS-449 before the Electronics Industries Association (EIA) and Telecommunications Industry Association (TIA) accepted them as standards.

T1 Cabling
Trunk cables connect the customer DSX-1 crossconnect point or T1-E1 Channel Service Unit (CSU) to the IGX node at the BC-T1 or BC-E1 back card. Refer to Table C-2 for details.
Table C-2 T1 Trunk/Circuit Line Cabling Specification
Cable Parameter
|
Description
|
Cable Type:
|
Western Electric 22 AWG, ABAM individually shielded twisted pair. Two pair per T1 line (1 transmit and 1 receive).
|
Cable Connector:
|
Male DB-15 subminiature. See for pinouts. The connector pinouts are the same for both the BA-T1 and the MT3 Distribution Panel.
|
Maximum Cable Length:
|
533 ft (162 m.) maximum between the node and the first repeater or CSU.

E1 Cabling
E1 trunk cables connect the customer DSX-1 crossconnect point or E1 Channel Service Unit (CSU) to the node at the back card. Note that variations exist in the pin assignments for some interfaces: and show the D-connector pinouts for the CVM, NTM, UFM, UVM, and FRM.
Table C-4 E1 Trunk/Circuit Line Cabling Specification
Cable Parameter
|
Description
|
Cable Type:
|
75-ohm coaxial cable for balanced line or 100-120-ohm twisted pair for unbalanced line. Balanced lines use two cables per E1 port.
|
Cable Connector:
|
Two female BNC for balanced connection; male DB-15 for unbalanced connection. See , , and for pinouts.
|
Max. Cable Length:
|
E1 output complies with G.703, so attenuation must not exceed -6dB at 1024 kHz (applies to 75 ohm coax or 120 ohm twisted pair). Maximum length is 100 meters between the IGX node and the first repeater or CSU.

The UFI-HSSI interface is native DCE. The interface pin assignment is done in such a way that the UFI interface can be connected to the HSSI interface of a Cisco-Router, which is a native DTE, using a straight pin-to-pin HSSI standard cable attached to a UFI back card or a Cisco Router in either DTE or DCE modes.
A UFI card in DCE mode can be connected to any DTE interface using the same standard Cisco cable.
When UFI is configured in DTE mode, it needs the HSSI-DTE cable to connect to a DCE interface.The wiring details are shown in for cable number 72-1265-01.

See and for Wire Lists for adapter cables for X.21 application. This adapter cable is available in two models: one is used when the HDM/SDI card set operates as a DCE and the other when the HDM/SDI operates as a DTE. It has a male DB-37 on the IGX end and a female DB-15 (DCE) or male DB-15 (DTE) on the user-end.

LDM EIA/TIA-232 Port Pin Assignments
lists the EIA/TIA-232 port pin assignments at the DB-15 connector on the LDM's LDI back card. The LDM card supports a limited subset of EIA control leads. The LDI always uses a DCE or DTE DB-15-to-DB-25 adapter cable. Refer to and for wiring lists and the pin-outs for the standard male DB-25 connector to the user data device.

Power Cabling
This section describes AC and DC power cabling between the IGX node and the power source. Source-end connector information is not available for all countries, so local codes must be known or obtained by either the customer or installer. describes AC power cabling. describes DC power cabling.
Table C-36 AC Power Cabling
Piece
|
Standard
|
Cable:
|
Cisco provides a 6-foot (1.8m), 3-conductor cord with an IEC 320 C-19 appliance coupler for mating with the IGX node on the system end. The other end of the power cord should be a grounding-type attachment plug as described in the paragraphs that follow.
|
Connector:
|
In North America and Japan:
For IGX 8320/8430: NEMA L6-20 Twist Lock
For IGX 8410: NEMA L6-20 Twist Lock or NEMA 5-15
For Continental Europe: CEE 7/7 (Schuko)
For Italy: CEI 23-16/VII (16 Amp plug)
For United Kingdom and Ireland: BS 1363
For Australia and New Zealand: AS 3112
For those countries not appearing in the preceding list, use a power cord with an IEC 320 C-19 appliance coupler for the system-end and an appropriate grounding-type attachment plug at the other end in accordance with local standards.
|
Table C-37 DC Power Cabling
Piece
|
Standard
|
Cable:
|
You provide a 3-conductor cord. The other end of the power cord should be a grounding-type attachment. The wire gauge is 10 to 12 AWG or 4 sq. mm.
|
Connector:
|
At the system end, Cisco provides a pluggable wire block with screw-type clamping for the three conductors. The customer or installer attaches the customer supplied wiring to this block.
|
SCM Cabling
SCM cabling connects the Network Management ports on the SCM to Cisco WAN Manager (formerly StrataView Plus) Network Management computers, control terminals, and modems. This cabling also provides the connection for an external clock source.
Auxiliary and Control Port Cabling
Interface:
|
The IGX SCM auxiliary and control ports are configured as an
EIA/TIA-232 DCE port.
|
Suggested Cable:
|
24 AWG, 25-pair. A straight-through EIA/TIA-232 cable is used for a terminal or printer connection. A null modem cable ( ) is needed when interfacing with modems on either port.
|
Cable Length:
|
50 feet (15 m.) maximum.

Null Modem Cable
shows a null modem cable that connects some of the 1200 and 2400 baud modems to the IGX Control and Auxiliary ports.
Figure C-1 Null Modem Cable
External Clock Input Cabling
Two separate clock inputs exist, and can be used simultaneously on the IGX. They are labelled External-1 and External-2. Both clock inputs require an EIA/TIA 422 balanced square wave signal at either 1.544 or 2.048 MB per second.
Note Standard DS1 or E1 BITS clock sources using AMI bipolar pulse stream signals are not compatible with IGX external clock inputs.

Standard IGX Cables
lists the cables you can order directly from Cisco Systems. The length of the cable appears as a suffix to the model number. For example 5610-50 indicates a 50-foot cable. Cables are generally available in standard lengths of 10 ft (3 m.), 25 ft (7.6 m.), 50 ft (15 m.), 75 ft (22.8 m.) and 100 ft (30 m.) Lengths of 101 ft. (30 m.) to 600 ft. (183 m.) are available on a special order.
Where applicable, indicates the connector gender (male-female) as well as the number of pins. For example T1/M15-M15 indicates a cable terminated with a male DB-15 at both ends.
