Provisioning Conventional TR-08 Voice Services

The Access Navigator’s Digital Crossconnect Switch (DCS) functions can provide basic support for existing TR-08 channel banks configured as Shelf B, C, or D channel units (see Figure 9-2). The Access Navigator/DCS can groom and fill DS1s with TR-08 voice channels, but will not per- form call concentration, signaling translation, or Shelf A data link management. (For provisioning the Access Bank® I/TR-08, see Provisioning TR-08 Service with GR-303 Translation on

page 10-5.)

Any number of TR-08 Shelf B, C, and D channel units can connect to the Access Navigator/DCS “drop” DS1s using D4 or ESF framing.

NOTE: ESF is not standard for TR-08. This option has been added to allow remote management of the Access Bank® II. See Provision Remote Access Bank II on page 11-1.

ATR-08/SLC-96 compatible switch connects to the Access Navigator “groom” DS1s using D4 framing (equivalent to SLC-96 SF framing). By crossconnecting the voice channels at the DS0 level, the Access Navigator is able to groom and fill the DS1s going to the TR-08 switch for most efficient use of DS1 resources.

DCS also works with drop DS1s carrying both voice and data channels. For example, an Access Bank II with Special POTS cards provides TR-08 voice channels as well as high-speed data over the same DS1. The Access Navigator can easily cross-connect the data channels to other groom DS1s providing access to Internet and other data services.
