  Before configuring the dial backup option, you need to plan your particular networking environment.

  Range: Enabled or Disabled

Switched Line Wait Timer

  This parameter defines the maximum amount of time the unit waits for the CSU/DSU to establish a dial connection before switching back to the dedicated line. The unit uses this value to determine if the connection was successful.
  Range: 1 -- 60 minutes

Dedicated Line Wait Timer

  The U.S. Federal Communications Commission (FCC) regulations for autodialers requires that the autodialer waits between successive dial operations. This parameter satisfies this requirement.
  This value defines the maximum amount of time the unit waits before retrying the dial operation. The timer begins when the port lowers its DTR. When the timer expires, the pot raises its DTR again and retries the operation.
  Range: 10 -- 120 minutes (with a one-minute resolution)

Alternate IP Subnet Address

  This address defines the alternate IP address for a single-port dial-up connection. The single-port dial-up connection is viewed as a back-to-back connection with DLCI 32 enabled.
  If this parameter is not defined, the primary IP address, defined at the port level, is used.
  Range: 4 numbers (0 -- 255) separated by three periods

Alternate IP Subnet Network Mask

  This parameter defines the address mask used for the alternate IP address.
  Range: 4 numbers (0 -- 255) separated by three periods
