ADTRAN SHDSL NxNTU specifications Cross-Connect Map

Cross-Connect Map

The purpose of the cross-connect map is to allocate the time slots (TS0s) from the SHDSL loop to user ports (E1, V.35/X.21) and configure framing. The cross-connect maps can be accessed via the VT100 terminal screens. Select “1,” Provisioning, from the Main Menu. Choose to provision the local unit (Selection 1) or the remote unit (Selection 2). Next, select “1,” Unit Options, and then “3,” Cross Connect Map. The cross-connect map is shown in Figure 6.

The cross-connect map is split down the middle in two sections. The left section of the map lists the SHDSL time slots and right section of the map lists the G.703 time slots. The user builds a new pending map before making it active with the apply key. The options listed at the bottom of the screen allow the user to setup and manipulate the time slots. The statement under the list of commands indicates the framing status. Time slot configuration options are defined as follows:

0. Idle

If a time slot is set for idle, an idle code is inserted. The pattern will always be FF hex (all 1s) toward the SHDSL network.

The idle pattern out the G.703 interface is programmable under the G.703 option. The default is value FF hex (all 1’s).

1. - 31. G.703 Service

The selected time slot will carry G.703 service (Refer to the Full G.703 Services subsection for more information).

32. G.704 Framing

This option enables three different framing configurations. Framing is always set in the first time slot (TS0). The framing will be locally generated if 32 is entered in the G.703 TS0 slot only. If 32 is entered in the G.703 TS0 and the SHDSL TS0, then the framing will be passed transparently between the G.703 and SHDSL ports. If values other than 32 are assigned to both the SHDSL TS0 slot and G.703 TS0 slot then the operation is G.703 unframed (if other G.703 service values are assigned to the G.703 time slots).

33. Nx64k Service

The selected time slot will carry Nx64k service. The value assignment is only valid for the SHDSL time slots.

A. Apply New Map

This command saves and activates any changes made by the user.

U. Undo New Map

This command will undo any changes made by the user since the last saved configuration. The new pending map will revert to the currently active time slot assignments.
