PA-8T-V.35 Synchronous Serial Port Adapter Installation and Configuration

Chapter 1 Overview
Identifying Interface Addresses
If the FlexWAN module is inserted in module slot 3, then the interface addresses of the PA-8T-V.35 are
3/0/0 through 3/0/7 (module slot 3, port adapter bay 0, and interfaces 0 through 7). If the port adapter
was in port adapter bay 1 on the FlexWAN module, these same interface addresses would be numbered
3/1/0 through 3/1/7.
Note If you remove the FlexWAN module with the PA-8T-V.35 from module slot 3 and install it in module
slot 6, the interface addresses become 6/0/0 through 6/0/7.
Note The FlexWAN module physical port address uses a zero- (0-) based port address, which differs from the
conventional Catalyst 6000 family one- (1-) based port address.
Cisco 7100 Series Routers Interface Addresses
This section describes how to identify the interface addresses used for the PA-8T-V.35 in Cisco 7100
series routers. The interface address is composed of a two-part number in the format
port-adapter-slot-number/interface-port-number. See Table 1-5 for the interface address format.
Cisco 7200 Series and Cisco uBR7200 Series Routers Interface Addresses
This section describes how to identify the interface addresses used for the PA-8T-V.35 in Cisco 7200
series routers or Cisco uBR7200 series routers. The interface address is composed of a two-part number
in the format port-adapter-slot-number/interface-port-number. See Table 1-5 for the interface address
format.
In Cisco 7200 series routers, port adapter slots are numbered from the lower left to the upper right,
beginning with port adapter slot 1 and continuing through port adapter slot 2 for the Cisco 7202, slot 4
for the Cisco 7204 and Cisco 7204VXR, and slot 6 for the Cisco 7206 and Cisco 7206VXR. (Port
adapter slot 0 is reserved for the optional Fast Ethernet port on the I/O controller—if present.)
The interface addresses of the interfaces on the PA-8T-V.35 in port adapter slot 1 are 1/0 through 1/7
(port adapter slot 1 and interfaces 0 through 7). If the PA-8T-V.35 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).
In Cisco uBR7200 series routers, port adapter slots are numbered slot 1 and slot 2 for the
Cisco uBR7246 and Cisco uBR7246VXR and slot 1 for the Cisco uBR7223. (Slot 0 is always reserved
for the Fast Ethernet port on the I/O controller—if present.) The individual interfaces always begin with
0. The number of additional interfaces depends on the number of interface ports on a port adapter.
The interface addresses of the interfaces on a PA-8T-V.35 in port adapter slot 2 are 2/0 and 2/1
(port adapter slot 2 and interfaces 0 and 1). If the PA-8T-V.35 was in port adapter slot 1, these same
interfaces would be numbered 1/0 and 1/1 (port adapter slot 1 and interfaces 0 and 1).
Cisco 7301 Router Interface Addresses
This section describes how to identify the interface addresses used for the Cisco PA-8T-V.35 port adapter
in Cisco 7301 router. The interface address is composed of a two-part number in the format
port-adapter-slot-number/interface-port-number. See Table 1-5 on page 1-21 for the interface address
format.
