However, when you move a VIP to a different slot, the interface processor slot number changes to reflect the new interface processor slot.
  • Page 37 Catalyst 6000 Family FlexWAN Module Interface Addresses This section describes how to identify the interface addresses used for the PA-8T-232 on the Catalyst FlexWAN module in the Catalyst 6000 family switches.The interface address is composed of a three-part number in the format module-number/port-adapter-bay-number/interface-port-number.

  • Page 38: Cisco 7200 Series And Cisco Ubr7200 Series Routers Interface Addresses

    The interface addresses of the interfaces on the PA-8T-232 in port adapter slot 1 are 1/0 through 1/7 (port adapter slot 1 and interfaces 0 through 7). If the PA-8T-232 was in port adapter slot 4, these same interfaces would be numbered 4/0 through 4/7 (port adapter slot 4 and interfaces 0 through 7).

  • Page 39: Cisco 7301 Router Interface Addresses

    If the VIP is inserted in interface processor slot 3, then the interface addresses of the PA-8T-232 are 3/1/0 through 3/1/7 (interface processor slot 3, port adapter slot 1, and interfaces 0 through 7). If the port adapter was in port adapter slot 0 on the VIP, these same interface addresses would be numbered 3/0/0 through 3/0/7.

  • Page 85: Setting The Clock Rate

    Setting the Clock Rate The default operation on a PA-8T-232 DCE interface is for the DCE device to generate its own clock signal (TxC) and send it to the remote DTE. The remote DTE device returns the clock signal to the DCE (the PA-8T-232).
  • Page 86 In the following example, a nonstandard clock rate of 1234567 bps is specified: Router(config-if)# clock rate 1234567 The preceding command example applies to all systems in which the PA-8T-232 is supported. Use the no clock rate command to remove the clock rate.

  • Page 87: Inverting The Clock Signal

    Inverting the Data Signal If you use an EIA/TIA-232 interface on the PA-8T-232 port adapter to drive a dedicated T1 line that does not have B8ZS encoding—a method to avoid 15 zeros—you must invert the data stream (both TXD and RXD) either in the connecting CSU/DSU or on the interface.

  • Page 88: Configuring Cyclic Redundancy Checks

    In the example that follows, NRZI encoding with no signal transition—with argument—is specified: Router(config-if)# nrzi-encoding mark The preceding command examples apply to all systems in which the PA-8T-232 is supported. Use the no nrzi-encoding command to disable NRZI encoding. When you are done, press Ctrl-Z—hold down the Control key while you press Z—or enter end or exit to exit configuration mode and return to the EXEC command interpreter prompt.

  • Page 90 Chapter 5 Configuring the PA-8T-232 Interfaces Configuring Half-Duplex and Binary Synchronous Communications in Cisco 7200 Series Routers waits a user-configured amount of time and then transmits the data. After the transmission, the interface waits a user-configured amount of time and then deactivates DCD. Constant-carrier mode activates DCD at all times.
