This configuration note contains instructions for installing and configuring the Fast Serial Interface
Processor (FSIP) in Cisco 7000 series or Cisco 7500 series routers. Included are basic configuration
steps and examples.
Note
yet developed. The Serial Interface Processor (SIP, SX-SIP, or PRE-FSIP) provided an interim
solution until the FSIP was released in September 1993 with Software Release 9.17(5). The FSIP is
now the default serial interface processor for Cisco 7000 series routers. The SIP can no longer be
ordered, and no new microcode or feature enhancements for it will be released. An FSIP upgrade
program is currently in progress to replace all SIPs in the field with new FSIPs. If you currently have
SIPs running in your Cisco 7000, we encourage you to replace them as soon as possible; the upgrade
is free of charge. Contact a service representative for information about the upgrade.
If you are replacing SIPs with new FSIPs, refer to the instructions in the document Replacing SIPs
with FSIPs in the Cisco 7000 (Document Number 78-1191-xx) before proceeding.
If you are installing a new FSIP in an installed Cisco 7000, ensure that your system meets the
required minimum configuration for FSIP operation before proceeding: Maintenance Release
9.17(5) and SP Microcode Version 1.4. (For a description of prerequisites, refer to the section

  • Page 4 FSIP Interface Types Additional port adapters are available as spares so that you can replace one that fails; however, you cannot upgrade a 4-port FSIP to an 8-port FSIP by adding port adapters. (The 4-port FSIP is not constructed to support additional ports after it leaves the factory; it contains the circuitry to control only one 4-port module.) An adapter cable provides the network connection for each port and determines the electrical interface type and mode of that interface.

The E1-G.703/G.704 port adapter supports point-to-point connections to Cisco 7000 series and Cisco 7500 series routers from 2.048-Mbps, E1 leased-line services, and eliminates the need for a separate, external data termination unit that is typically used to convert standard serial interfaces, such as V.35, to E1-G.703/G.704.

  • Page 14 FSIP Installation Prerequisites We recommend that you install interface processors starting with the slots closest to the RSPs Note and work out concentrically from there. This will help to ensure that rejection of electromagnetic interference (EMI) is maintained. All interface processors have ejector levers that allow you to firmly seat an interface processor in the interface processor slot (see Figure 8).

  • Page 30 FSIP Port Adapters, Interface Cables, and Connections EIA/TIA-449 Connections EIA/TIA-449, which supports balanced (EIA/TIA-422) and unbalanced (EIA/TIA-423) transmissions, is a faster (up to 2 Mbps) version of EIA/TIA-232, which provides more functions and supports transmissions over greater distances. The EIA/TIA-449 standard was intended to replace EIA/TIA-232, but it was not widely adopted.
  • Page 31 FSIP Port Adapters, Interface Cables, and Connections X.21 Connections The X.21 interface uses a 15-pin connection for balanced circuits and is commonly used in the United Kingdom to connect public data networks. The X.21 interface relocates some of the logic functions to the DTE and DCE interfaces and, as a result, requires fewer circuits and a smaller connector than EIA/TIA-232.
  • Page 32 FSIP Port Adapters, Interface Cables, and Connections Metric Thumbscrews A pair of metric thumbscrews is included with each port adapter cable except V.35. If you plan to connect serial cables to a remote device that uses metric hardware, replace the standard 4-40 thumbscrews at the network end of the cable with the metric, M3 thumbscrews.
  • Page 33 FSIP Port Adapters, Interface Cables, and Connections Attaching Network Interface Cables to the FSIP All FSIP ports support any available synchronous serial interface type and mode. The serial adapter cable determines the electrical interface type and mode of the port to which it is connected. E1-G.703/G.704, EIA/TIA-232, EIA/TIA-449, V.35, and X.21 interfaces are available in DTE mode with a plug at the network end and in DCE mode with a receptacle at the network end.
  • Page 34 Using LEDs to Check FSIP Status Using LEDs to Check FSIP Status The FSIP has several status LEDs on its faceplate, next to each port, which indicate conditions on that port. (See Figure 22.) Figure 22 FSIP LEDs After system initialization, the enabled LED goes on to indicate that the FSIP has been enabled for operation.

  • Page 36 Using LEDs to Check FSIP Status The following LED state descriptions include meanings for both DTE and DCE interfaces: • RxC—On both DTE and DCE interfaces, this LED is on when the port is receiving an external clock signal. • RxD—On both DTE and DCE interfaces, this LED is on when the port is receiving data signals (packets) from the network.
  • Page 37 Interface Port Numbering for the FSIP Serial Interfaces Cisco 7000 series and Cisco 7500 series routers identify an interface address by its interface processor slot number and port number in the format slot/port. Each FSIP contains either four or eight serial interfaces.
  • Page 38 Configuring the FSIP Configuring the Interfaces The following instructions are provided for performing a basic configuration: enabling an interface, specifying IP routing, and setting up external timing on a DCE interface. You might also need to enter other configuration subcommands, depending on the requirements for your system configuration and the protocols you plan to route on the interface.
  • Page 39 Configuring the FSIP Configuring Timing (Clock) Signals All interfaces support both DTE and DCE mode (except the EIA/TIA-530 interface, which is DTE only). The mode of the interface cable attached to the port. To use a port as a DTE interface, you must connect a DTE adapter cable to the port.
  • Page 40 Configuring the FSIP In the example that follows, the first serial port on an FSIP in interface processor slot 0 is configured to accept the internal clock signal: Router(config)# interface serial 0/0 Router(config-if)# transmit-clock-internal When the FSIP port is a DTE, the invert-transmit-clock command inverts the TxC signal it receives from the remote DCE.
  • Page 41 Configuring the FSIP To enable 32-bit CRC on an interface, specify the slot and port address of the interface followed by the command crc32. In the example that follows, the first serial port on an FSIP in interface processor slot 0 is configured for 32-bit CRC: Router# configure terminal Enter configuration commands, one per line.
  • Page 42 Configuring the FSIP Time slot 0, or the first 8 bits, is reserved as overhead. The remaining 248 bits (31 frames with 8 bits each) are designated time slots 1 through 31. Time slot 16 is also designated as a framing slot when using framed mode.
  • Page 43 Configuring the FSIP In the example that follows, the first port on an FSIP in interface processor slot 0 is configured for CRC-4: Router# configure terminal Enter configuration commands, one per line. End with CNTL/Z. Router(config)# interface serial 0/0 Router(config-if)# crc4 Ctrl-Z To disable CRC and return an interface to the default of no CRC error checking, specify the interface and use the no crc4 command.
  • Page 44 Configuring the FSIP Configuring E1-G.703/G.704 Loopback The E1-G.703/G.704 interface supports the same local loopback test as the other (data communications) FSIP interfaces. Loopback functions enable you to check the integrity of the physical data path between the FSIP and the E1 port adapter with the loopback command. The no loopback command disables all loopback tests on the interface.
  • Page 45 Configuring the FSIP At system startup or restart, the FSIP polls the interfaces and determines the electrical interface type of each port (according to the type of port adapter cable attached). However, it does not necessarily repoll an interface when you change the adapter cable online. To ensure that the system recognizes the new interface type, shut down and reenable the interface after changing the cable.
  • Page 46 Configuring the FSIP Using Show Commands to Check the Configuration The following summary describes how to use the show commands to verify that the new interfaces are configured correctly: Step 1 Use the show version command to display the system hardware configuration. Ensure that the list includes the new interfaces.
