Cabling Specifications

Cabling Specifications

This appendix lists the pinouts for ports on the RP (or RSP7000), EIP, TRIP, FIP, and MIP and for the serial interface cables that connect each FSIP and HSSI port to the external network.

All pins not specifically listed are not connected.

Following is a list of the signal summaries contained in this appendix:


Note All FSIP ports use the same high-density, 60-pin receptacle (except for the E1-G.703/G.704 port adapter, which uses DB-15 connectors). Each port requires a serial port adapter cable, which determines the port's electrical interface type and mode: data terminal equipment (DTE) or data circuit-terminating equipment (DCE). Although all port adapter cables use a high-density 60-pin plug to connect to the FSIP port, the network end of each cable type uses the physical connectors commonly used for the interface. (For example, the network end of the EIA/TIA-232 port adapter cable is a DB-25, which is the most widely used EIA/TIA-232 connector.)

Console Port Signals

Thee console port on the RP (or RSP7000) is an EIA/TIA-232, DCE, DB-25 receptacle. Both DSR and DCD are active when the system is running. The RTS signal tracks the state of the CTS input. The console port does not support modem control or hardware flow control. Table A-1 lists the signals used on this port. The console port requires a straight-through EIA/TIA-232 cable.

Auxiliary Port Signals

The auxiliary port on the RP (or RSP7000) is an EIA/TIA-232, DTE, DB-25 plug to which you attach a CSU/DSU or other equipment in order to access the router from the network. Table A-2 lists the signals used on this port.

The auxiliary port supports hardware flow control and modem control.

Ethernet Connector Signals

Most Ethernet transceivers require an attachment unit interface (AUI) or transceiver cable to connect an Ethernet transceiver to the EIP Ethernet ports. Some unshielded twisted-pair (10BaseT) transceivers are compact enough to connect directly to the EIP ports without impeding other connections. For descriptions of Ethernet transceivers, connectors, and cables refer to the section "Ethernet Connection Equipment" in the chapter "Preparing for Installation."

Table A-3 lists the signals for the 15-pin Ethernet connector used on the EIP.

Fast Ethernet Connector Signals

The two connectors on the FEIP are a single MII, 40-pin, D-shell type, and a single RJ-45. You can use either one or the other. Only one connector can be used at one time. Each connection supports IEEE 802.3u interfaces compliant with the 100BaseX and 100BaseT standards. The RJ-45 connection does not require an external transceiver; however, the MII connection does.

The RJ-45 modular connector has strain relief functionality incorporated into the design of its standard plastic connector. Table A-4 and Table A-5 list the pinouts and signals for the RJ-45 and MII connectors.

Note Referring to the RJ-45 pinout in
Table A-4, proper common-mode line terminations should be used for the unused Category 5, 100-ohm UTP cable pairs 4/5 and 6/7. Common-mode termination reduces the contributions to electromagnetic interference (EMI) and susceptibility to common-mode sources. Wire pairs 4/5 and 6/7 are actively terminated in the RJ-45, 100BaseTX port circuitry in the FEIP port adapter.

Token Ring Port Signals

A network interface cable provides the connection between the 9-pin Token Ring connectors on the TRIP and a media access unit (MAU). The 9-pin connector at the TRIP end, and the MAU connector at the network end, are described in the section "Token Ring Connection Equipment" in the chapter "Preparing for Installation." Table A-6 lists the signals for the DB-9 Token Ring connector used on the TRIP.

FDDI Optical Bypass Switch Signals

Table A-7 lists the signal descriptions for the mini-DIN optical bypass switch available on the multimode/multimode FIP (Cx-FIP-MM) and the single-mode/single-mode (CX-FIP-SS) FIP. The mini-DIN-to-DIN adapter cable (CAB-FMDD) allows connection to an optical bypass switch that uses a DIN connector (which is larger than the mini-DIN connector on the FIP).

Serial Adapter Cable Pinouts

The FSIP supports EIA/TIA-232, EIA/TIA-449, X.21, V.35, and EIA-530 serial interfaces.

All FSIP ports use a universal port adapter, which is a 60-pin receptacle that supports all available interface types. (The exception to this is the E1-G.703/G.704 port adapter, which uses a DB-15 connector.) A special serial adapter cable, which is required for each port, determines the electrical interface type and mode of the interface. The router (FSIP) end of all of the adapter cables is a 60-pin plug; the connectors at the network end are the standard connectors used for the respective interfaces.

All interface types except EIA-530 are available in DTE or DCE format: DTE with a plug connector at the network end and DCE with a receptacle at the network end. V.35 is available in either mode with either gender at the network end. EIA-530 is available in DTE only.

The tables that follow list the signal pinouts for both the DTE and DCE mode serial port adapter cables for each FSIP interface type.

HSSI Connector Signals

Two types of cables are available for use with the HIP: the HSSI interface cable used to connect the HIP HSSI port with an external DSU (and HSSI network) and a null modem cable, which allows you to connect two collocated routers back to back.

HSSI Interface Cable

The HSSI interface cable (Product Number CAB-HSI1) connects the HIP port with an external DSU. The cable comprises 25 twisted pairs and a 50-pin SCSI-II-type plug at each end. Although the HSSI cable is similar to a SCSI-II cable, it is not identical; you cannot substitute a SCSI-II cable for a HSSI interface cable (see the following Caution).

Table A-14 lists the pin signals for the connector.

Caution Although the HIP connector and the HSSI interface cable are similar to SCSI-II format, the HSSI cable specification is more stringent than that for a SCSI-II. We cannot guarantee proper operation if a SCSI-II cable is used instead of an HSSI interface cable.

Null Modem Cable

The null modem cable (CAB-HNUL) can connect two routers directly back to back. The two routers must be in the same location and can be two Cisco 7000s, two AGS+ routers, or one of each. A null modem connection allows you to verify the operation of the HSSI or to link the routers directly in order to build a larger node.

The null modem cable uses the same 50-pin connectors as the HSSI interface cable, but uses the pinouts listed in Table A-15. For null modem cable connection and configuration instructions, refer to the section "HSSI Connection Equipment" in the chapter "Preparing for Installation."

MIP Interface Cable Pinouts

The MIP interface cables have two, male, 15-pin DB connectors (one at each end) to connect the MIP with the external CSU. Table A-16 lists the pinouts for the null-modem T1 cable, and
Table A-17 lists the pinouts for the straight-through T1 cable. Table A-18 lists the pinouts for the E1 interface cables.
