Applications/Solutions
Optical Interface on Front Panel
T1/J1/E1 Access
TDM and I-TDM Interface
- 155Mbps OC3/STM1 line interface on standard OC-3/OC-12 SDH STM-1 connectors
- 622Mbps OC-12/STM-4 line interface on standard OC-3/OC-12 SDH STM-4 connectors
VT/TU Access
- OC-3/SMT1 and OC-12/STM-4 framers connected to an add/drop multiplex/demultiplex chipset
- Access to VT/TU tributary unit groups within the VC3, VC4 and VC4-4c virtual containers
- Extract/insert of 84 T1/J1 or 63 E1 streams (NAMC-STM-1) or 4x 84 T1/J1 or 4x 63 E1 streams (NAMC-STM4) including respective clocking information contained in a single STM-1 or STM-4 SDH frame
- Supported mappings: VT1.5/VT-2 or TU-11/TU-12 to VC3/VC4/VC4-4c or STM4/STM4c
T1/J1/E1 Access
- NAMC-STM1: 84 T1/J1 or 63 E1 framers
- NAMC-STM4: 4x84 T1/J1 framers or 4x63 E1 framers
- Individual Rx/Tx, CLK and SYNC signals
- T1 framing standards: SF, SLC-96 and ESF
- E1 framing standards: G.704 and G.706 (CRC-4 multiframe)
- J1 framing standards: TTC JT-G.704 as well CRC-6 calculation
- Full jitter attenuation
TDM and I-TDM Interface
- E1/T1/J1 framer interfaces to the on-board timeslot interchanger (TSI) chipset
- Incorporated TSI and TDM-to-I-TDM bridge (on-board FPGA)
- Flexible routing and multicasting of 64kbps timeslots between the various E1/T1/J1 streams (TSI)
- TDM-to-I-TDM bridge converts the TDM oriented bit stream into Ethernet packets and vice versa
- Ethernet packets are sent and received via either the AMC ports 0 or 1 (selectable) 1000BaseT-BX Ethernet interface (Fabric A).
- Optional 32MHz clocked H.110-like TDM backplane interface on the AMC extended connector (TSI)
