G. Full G.703 Service

If this quick key command is selected, the cross- connect map will automatically configure the time slots for Full G.703 service, and the framing will be set for transparent. Refer to the Typical Applications subsection for more information.

N. Full Nx64k Service

If this quick key command is selected, the cross-connect map will automatically configure the time slots for full Nx64k service. Refer to the Typical Applications subsection for more information.

Tab. Select SHDSL or G.703 Timeslots

The tab key moves the cursor between the SHDSL and G.703 sections of the cross-connect map.

Arrow Keys. Move Cursor

The arrow keys allow movement between the individual time slots.

G.703 Service Time Slots

A service is comprised of an arbitrary collection of time slots from the SHDSL interface that shall be configured via the management interface. Time slot allocation on an ordered noncontiguous basis is possible with each time slot within a service having the same delay. An example is illustrated in Figure 7.

All unused time slots contain a configurable bit pattern that is set via the management interface. The default bit pattern is all 1s. Unused time slots are those which are sent out of the G.703 port, but are not part of a service. The G.703 port transmits the unused time slot patterns, and the receive ignores the unused time slots.

The service values (1-31) correlate to the G.703 Services test options. These options provide the capability to loopback and test time slots by service value, so as not to affect other services in surrounding time slots.
