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.

T3/E3 Cabling

T3/E3 cables connect to the single-port back cards AIT-T3 or AIT-E3 for the BTM or UAI-1T3-BC or UAI-1E3-BC for the ALM. These cables can connect a back card to either a DSX-3 cross-connect point, another back card in a co-located node, or a BPX node at the LM-3T3 back card. The only multi-port T3/E3 cards are UXM back cards. For descriptions of the UXM cables, see the section titled "UXM Cabling."

Cable Parameter	Description
Type:	75-Ohm coax cable (RG-59 B/U for short runs, AT&T 734A for longer runs). Two per T3/E3 line (XMT and RCV). The chosen cable has frequency/attenuation characteristics that follow a f law with a maximum attenuation of 6 dB at 1024 KHz.
Max. Length:	450 feet max. between the BTM back card and the DSX-3 point, or BTM trunk card.
Connector	Female BNC; Rx is receive T3/E3 to BTM back card, Tx is transmit T3/E3 to DSX-3 cross-connect.

See Table C-29 and Table C-30 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

Table C-32 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 Table C-33 and Table C-34 for wiring lists and the pin-outs for the standard male DB-25 connector to the user data device.

1. You can order this cable in lengths of 10 ft., 25 ft., 50 ft., 75 ft., and 100 ft. The Cisco model number is CAB-5626E-xx, where xx is the length, as follows: 10=10 ft.; 25=25 ft.; 50=50 ft.; 75=75 ft., and 00=100 ft.
2. You can use one of these pins to force a control pin to stay high or low.
3. No LDI local loop output is available. Try using DTR output: DB15-9.

Note Two adapter cables are available for the LDI card. The choice of cable determines whether the LDI card functions as a DCE or as a DTE. These may be ordered from Cisco Systems or made by the customer. Make sure the correct cable is used for the type of user device connected.

1. You can order this cable in lengths of 10 ft., 25 ft., 50 ft., 75 ft., and 100 ft. The Cisco model number is CAB-5625-xx, where xx is the length, as follows: 10=10 ft.; 25=25 ft.; 50=50 ft.; 75=75 ft., and 00=100 ft.
2. Pins 15 and 17 connect through a jumper.
3. You can use one of these pins to force a control pin to stay high or low.

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. Table C-36 describes AC power cabling. Table C-37 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 (Figure C-1) is needed when interfacing with modems on either port.
Cable Length:	50 feet (15 m.) maximum.
Cable Connector:	DB-25, subminiature, male. Table C-38 contains a list of the port pin assignments.

Null Modem Cable

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.

External Alarm Cabling

This cable connects network alarm outputs to either the DTI Faceplate or the ARI card Alarm connector. Table C-41 lists particulars for the physical interface. Table C-42 lists the pinouts for the network alarm outputs. In Table C-42, note that pins whose names end in "A" are normally open, and pins whose names end in "C" are common.

Standard IGX Cables

Table C-43 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, Table C-43 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 DB15 at both ends.
