Introduction 58Models 2616RC, 3096RC & 3196RC Admin Reference Guide 5 • DS0 MappingIntroductionTo route traffic from one device connected to the T-DAC to another device (also connected to the T-DAC) youmust define a DS0 mapping (also called an internal connection or cross-connection). An internal cross-connectioncarries traffic between the two external devices via the T-DAC. The external devices can be (but are not limitedto) a T1/E1 NTU, a G.SHDSL customer premise equipment (CPE) modem, or another blade in the sameCPCI chassis in which the T-DAC is installed.The T-DAC’s DS0 Mapping Overview window (see figure 19) provides the means for managing (mapping)internal connections.Note DS0 Mapping device and port options for the T-DAC family ofproducts are as follows:• 3096RC—G.SHDSL ports (16), T1/E1 ports (up to 16), andH.110 ports (32)• 3196RC— iDSL ports (16), T1/E1 ports (up to 16), and H.110ports (32)• 2616RC—T1/E1 ports (16), H.110 ports (32)Because of the similarities between TDACs, DS0 and fallback map-ping examples presented in this chapter are generic and meant to beused only as a guide—apply DS0 mapping to your particular T-DACas appropriate.Figure 19. DS0 Mapping Overview windowExternal devices can connect to the T-DAC via a T1/E1 WAN port, a DSL port, or an H.110 port. (A devicewill connect to an H.110 port via the T-DAC’s interface to the H.110 bus in the cPCI chassis midplane). EachDS0 mapping defines a one-to-one connection between a selected number of timeslots on one port and a cor-responding number of timeslots on a different port. You can use the DS0 Mapping management web page todefine these DS0 mappings (internal connections) and to view previously defined mappings.
