Switched Line Using Switched Floating PU and LU
Objects
Switched Line Using Switched Floating PU and LU Objects
Another way to configure switched lines is to allocate a pool of PU and LU objects to
the SNAX subsystem. These objects are called switched floating PU and LU
objects. These PU and LU objects are associated with a remote PU and LU only when
a switched connection is established.
Figure 3-5
on page 3-7 shows an example of a switched line using switched floating
PU and LU objects. The SCF configuration, shown alongside, configures the SNAX/XF
LINE, PU, and LU objects.

Notes. In this example, note the following LINE attributes:
1. INTERFACE V25 enables the line to use a V.25 bis modem that can send or receive calls
over a switched public telephone network.
2. DIALTYPE INOUT allows both incoming and outgoing calls.
3. AUTOACCEPT ON allows incoming calls without an application issuing CONTROL 11.
Note. For remote node verification through SDLC exchange identifier (XID) frames when
multiple remote nodes connect at different times on the same line, you must use switched
floating PU and LU objects.
