Page 14 After system initialization, the Enabled LED goes on, indicating that the port adapter has been enabled for operation. The following conditions must be met before the PA-T3 serial port adapter is enabled: • The port adapter contains a valid microcode version that has been downloaded successfully.
Page 15: Pa-T3 Receptacles And Cables
PA-T3 serial port adapter are considered to be data terminal equipment (DTE) devices. On a single PA-T3 serial port adapter, there are one or two T3 serial ports, each with two connectors (receive and transmit), where you connect the Cisco 75-ohm coaxial cable. The 75-ohm coaxial cable (Cisco part number CAB-ATM-DS3/E3) for the PA-T3 serial port adapter is available only from Cisco Systems;...

The second number identiﬁes the interface port on each PA-T3 serial port adapter; the interface port is always numbered as interface 0 for the one-port PA-T3 serial port adapter and 0 or 1 for a two-port PA-2T3 serial port adapter.
Page 47 Fast Ethernet port in a Cisco 7202, the system software automatically disables the port. For example, the serial port on a one-port PA-T3 serial port adapter in port adapter slot 3 has the address 3/0. (See Figure 8-1.) If the PA-T3 serial port adapter is in port adapter slot 1, this same interface port is numbered 1/0.
Page 48 • The third number identiﬁes the interface port on each PA-T3 serial port adapter, which is always numbered as interface 0 for the one-port PA-T3 serial port adapter and 0 or 1 for the two-port PA-T3 serial port adapter. Interface ports on the VIP2 maintain the same address regardless of whether other interface processors are installed or removed.
Page 49 For example, the serial port on a one-port PA-T3 serial port adapter in the ﬁrst port adapter slot in chassis slot 3, is numbered 3/0/0. (See Figure 8-3.) If the PA-T3 serial port adapter is in port adapter slot 1, this same port is numbered 3/1/0. The serial ports on a two-port PA-T3 serial port adapter in the ﬁrst port adapter slot in chassis slot 3 are numbered 3/0/0 and 3/0/1.

Page 56: Enabling T3 Scrambling
You need to know what type of DSU is at the remote port to ﬁnd out if it interoperates with the PA-T3 port adapter. For T3 serial interfaces, specify mode 0 for connection from a T3 serial port adapter to another PA-T3 serial port adapter or a Digital Link DSU (DL3100). Specify mode 1 for connection from a PA-T3 serial port adapter to a Kentrox DSU.
