Model 6511RC User Manual | 1 • Introduction |
| |
The Model 6511 communicates with the other blades installed and operating in the same segment over the H.110 TDM and PICMG 2.16 packet busses residing in the chassis mid-plane.
Matrix Switch functionality
The Model 6511 provides the following functionality:
•TDM mapping and aggregation—The Model 6511RC Matrix Switch concentrates the traffic capacity of up to 63 E1 lines for delivery on a 155.54 Mbps optical or electrical STM-1 uplink (see section “TDM mapping and aggregation” for details)
•TDM bus architecture—The Matrix Switch provides an interface to the H.110 bus within the ForeFront chassis.The total capacity of the H.110 bus is 4096 half-duplex DS0 channels, the equivalent of 64 E1 lines (see section “TDM bus architecture” for details)
•STM-1 link architecture—The 155.52 Mbps STM-1 uplink carries 2016 full-duplex (4032 half-duplex) DS0 channels organized into 63 E1 signal streams. Each E1 stream carries 32 full-duplex DS0 channels (64 half-duplex timeslots). The total capacity of the STM-1 uplink on the Model 6511RC is 2016 full-duplex DS0s, the equivalent of 63 E1 lines (see section “STM-1 link architecture” on page 22 for details)
•Matrix Switch TDM capacity—The Matrix Switch provides the means for you to map any DS0 on the H.110 TDM bus to any DS0 on the STM-1 trunk and vice-versa (see section “Matrix Switch TDM capac- ity” on page 23 for details)
TDM mapping and aggregation
The Model 6511RC Matrix Switch concentrates the traffic capacity of up to 63 E1 lines for delivery on a
155.54Mbps optical or electrical STM-1 uplink. For E1 traffic aggregation, the Matrix Switch performs mul- tiplexing and demultiplexing for all 63 E1 lines comprising the 155.52 Mbps STM-1 uplink. Each E1 line comprises 32 DS0 timeslots. Each timeslot comprises a 64 kbps communication channel, or DS0. The Model 6511RC delivers a fully non-blocking switching matrix to the ForeFront system, providing any-to-any map- ping between all 4096 half-duplex DS0 timeslots carried in the H.110 bus and all 4032 half-duplex DS0 timeslots in the SDH STM-1 uplink.
