Framing and FDL Settings
SLC-96 uses two types of framing: SLC-96 DLL and SLC-96 S4. The combination of setting for
the framing type and FDL protocol determine which framing type will be used for the drop DS1.
For Shelf A, the DS1 FDL protocol is set to “slc96” to obtain SLC-96 DDL framing with its out-
of-band data link management channel. For Shelf B, C, and D, the FDL is set to “none” to obtain
standard SLC-96 S4 (or D4) framing.
Access Bank I/TR-08 Switch Settings
When installing the Access Bank I/TR-08, Switch 4 (framing) on its front panel is set OFF for Shelf
A, or set ON for Shelf B, C, D. Response to loopback code patterns presented over the DS1 (T1)
line also depends on the settings of Switch 4 and Switch 6. Because there are no interconnections
between shelves, alarm monitoring is only available for Shelf A. If desired, all units can be
configured as Shelf A when using GR-303 to TR-08 translation.
Special TR-08 Settings
GR-303 provisioning for TR-08 Shelf B, C, D support requires the following settings for the DS1
drop lines. Other GR-303 settings remain the same. See GR-303 Provisioning Quick Guide on
page 10-9 .
