Programming the network interface
Switch pack 2 is used to program the Network Interface (NI). The
following is a description of the Network Interface settings:
Table 3-2 C100 and C150 Switch-2: Network Interface
NI Framing Switch pack 2 position 1 determines the type framing. With position 1
Off, the unit will generate and expect ESF framing to and from the
Network Interface. With position 1 On, the unit will generate and
expect D4 framing. The framing selected in the unit must match the
framing option provided by the T-1 Carrier
NI Coding Switch pack 2 position 2 selects the type of coding the unit will
generate. Position 2 Off, makes the unit generate B8ZS encoding and in
the On position causes the unit to generate AMI (Alternate Mark
Inversion) encoding. This coding selection, similar to the framing,
must match the provisioning provided by the T-1 Carrier supplier
otherwise intermittent errors may occur.
