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.

Switch 4	Switch 6	Shelf	Access Bank I/TR-08
			Loopback Code Response
OFF	OFF or	A	Responds only to FDL (SLC-96 DDL) loopback codes
	ON
ON	OFF	B, C, D	Responds to CSU loopback codes
ON	ON	B, C, D	Does not respond to CSU loopback codes

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.
