Dedicated, dial-up business telephone line for TAC-to-IGX modem and auto-dial-to-TAC modem
Auto-answer is a setup in which the Cisco TAC can dial into the switch. Using the cnfterm command, set the IGX Control port speed to 9600 bps. Using the cnftermfunc command, set the terminal type to VT100/StrataView. To program the modem, temporarily attach a terminal to the modem using a null modem cable. The modem EIA port automatically matches the 9600 bps setting of the terminal. Enter the commands listed in Table A-7 to set up the modem for proper operation.

Cabling Summary
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.
WarningTo prevent accidental discharge in the event of a power line cross, route on-premise wiring away from power cables and off-premise wiring, or use a grounded shield to separate the on-premise wiring from the power cables and off-premise wiring. A power line cross is an event, such as a lightning strike, that causes a power surge. Off-premise wiring is designed to withstand power line crosses. On-premise wiring is protected from power line crosses by a device that provides overcurrent and overvoltage protection. Nevertheless, if the on-premise wiring is in close proximity to, or not shielded from, the off-premise wiring or power cables during a lightning strike or power surge, the on-premise wiring can carry a dangerous discharge to the attached interface, equipment, and nearby personnel. To see translations of this warning, refer to the Regulatory Compliance and Safety Information document that accompanied this product.

Cabling for the UFM-U Back Cards
This section describes the standard cabling and the Y-cabling scheme for the unchannelized back cards. The back cards are the UFI-12V.35, UFI-12X.21, and UFI-4HSSI. Because of the port variety and because the cables are either DCE or DTE, a significant number of cable configurations exist. Table A-26 shows cable names, part numbers, and descriptions.
The connectors on the UFI cards are high density. Each UFI-12V.35 and UFI-12X.21 card has six 60-pin connectors. Each of these connectors has two ports. If your specification dictates that both ports on a connector are active, you must have a cable with wiring for two ports. If a part number in Table A-26 has the form "CAB-2...," the cable has wiring for two ports. Note that if both ports on a connector are active, both ports must be either DCE or DTE, because the cable itself is either DCE or DTE. If a connector has only one active port, the cable can be the less expensive, single-port version. An HSSI connector has 50 pins and supports one port.

Port redundancy through the use of a Y-cable requires two card sets, at least one Y-cable, and the standard cabling. On a UFI-4HSSI, Port 1 is the only port that supports Y-cable redundancy. On the V.35 and X.21 UFIs, redundancy at more than one connector requires a corresponding number of Y-cables and standard cables. The standard cables are either single-port for HSSI, V.35, or X.21 or dual-port for the X.21 and V.35 UFIs.
To set up the Y-cabling, you attach a branch of the Y at the primary and redundant connectors then attach the near end of the standard cable to the base of the Y. Figure A-3 illustrates single and dual-cabling in a Y-cable setup. The single-cable arrangement applies to HSSI, V.35, and X.21. The dual-port redundancy setup applies to a UFI-12X.21 or UFI-12V.35, where both ports within the UFI connector are used in a Y-cable redundancy scheme.

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 Table A-32 for cable number 72-1265-01.

LDM EIA/TIA-232 Port Pin Assignments
Table A-41 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 A-42 and Table A-43 for wiring lists and the pin-outs for the standard male DB-25 connector to the user data device.
1You can use one of these pins to force a control pin to stay high or low.
2No LDI local loop output is available. Try using DTR output: DB-15-9.
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 can be ordered from Cisco Systems or made by the customer.
Make sure that the correct cable is used for the type of user device connected.

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 the installer. Table A-45 describes AC power cabling. Table A-46 describes DC power cabling.
Table A-45 AC Power Cabling
Piece
Standard
Cable
Cisco provides a 6-ft (1.8 m), 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 A 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 A-46 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 A-4) is needed when interfacing with modems on either port.
Cable length:
50 ft (15 m) maximum.
Cable connector:
DB-25, subminiature, male. Table A-47 contains a list of the port pin assignments.

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.

This cable connects network alarm outputs to either the DTI Faceplate or the ARI card alarm connector. Table A-50 lists particulars for the physical interface. Table A-51 lists the pinouts for the network alarm outputs. In Table A-51, note that pins whose names end in "A" are normally open, and pins whose names end in "C" are common.
Table A-52 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 through special order.
Where applicable, Table A-52 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.
Note Most cables listed as T1 can also be used for E1 service.
Note Transmit direction is towards the Y trunk.
