This appendix provides details on the IGX cabling required to connect customer devices and lines to the IGX node.
Trunk cables connect the customer DSX-1 crossconnect point or T1-E1 Channel Service Unit to the IGX node at the BC-T1 or BC-E1 back card. Refer to Table C-1 for details.
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 Table C-2 for pinouts. The connector pinouts are the same for the both the BA-T1 and for the MT3 Distribution Panel. |
Max. Cable Length: | 533 ft (162 m.) maximum between the IGX and the first repeater or CSU. Selection of cable length equalizers. |

E1 trunk cables connect the customer DSX-1 crossconnect point or E1 Channel Service Unit to the IGX node at the BC-E1 back card.
Cable Parameter | Description |
---|---|
Cable Type: | 75-ohm coax cable for unbalanced connection or 100-120-ohm twisted pair for balanced connection. Two cables/pairs (1 transmit, 1 receive) per E1 line. |
Cable Connector: | Two female BNC for unbalanced connection; male DB15 for balanced connection. See Table C-4 and Table C-5 for pinouts. |
Max. Cable Length: | E1 output complies with G.703, so cabling must not exceed -6dB/1000 feet at 1024 kHz (applies to 75 Ohm coax or 120 Ohm twisted pair up to 350 meters or 1000 feet). Cisco supplies cable with a maximum attenuation of 7 dB /1000 ft., so the maximum length of this cable is 850 feet (260 meters). |

This section describes AC and DC power cabling between the IGX 8 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.
Cable: | Cisco provides a 6-foot (1.8m), 3-conductor cord with an IEC 320 C-19 appliance coupler for mating with the IGX 8 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: | For North America and Japan: NEMA L6-20 Twist Lock 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. |
This cabling connects the Network Management ports on the SCM to StrataView Network Management computers, control terminals, and modems. It is also used for external clock inputs from a clock source.
Interface: | The IGX SCM auxiliary and control ports are configured as an RS-232 DCE port. |
Suggested Cable: | 24 AWG, 25-pair. A straight-through RS-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.) max. |
Cable Connector: | DB-25, subminiature, male. Table C-25 lists port pin assignments. |

Figure C-1 shows a null modem cable that connects some of the 1200 and 2400 baud modems to the IGX Control and Auxiliary ports.
This cable connects external clock inputs to the SCM EXT. CLK. connector. Its two separate inputs are A and B, for primary and standby clock sources. Either or both of these may be 1.544 Mbps or 2.048 Mbps. The SCM automatically selects clock input A or B.

Table C-30 lists the various cables that may be ordered directly from Cisco. Cable lengths are specified as a suffix to the IGX 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.
When applicable, the connector gender (male-female) will be indicated as well as the number of pins. For example T1/M15-M15 indicates a cable terminated with a male DB15 at both ends.
