Thiết bị STM 1/4 Loop O9550
The Loop-O9550 SDH/SONET IMAP (Integrated Multi-Service Access Platform) is an economical STM-1/4 (OC-3/12) access multiplexer. It is designed to combine digital access interfaces, including TDM, IP, and voice interfaces into STM-1/4 (OC-3/12) optical lines for convenient transport and switching.
- 5U height, full front access (ETSI) shelf
- ADM, TM, and cross-connect
- STM-1/4 (OC-3/12) optical ring uplinks
- Up to four STM-1/4 (OC-3/12) aggregate lines that are software configurable
- For uplink site, non-blocking N x 64 Kbps are 252 E1 or 336 T1 for data and voice channel transmission
- For tributary site, non-blocking N x 64 Kbps are maximum 64 E1 or 52 T1 for data and voice channel transmission
- Total Non-blocking N x 64K bps N=316E1 (252E1 + 64E1)
- Tributary modules (didigal access interfaces including TDM, IP and Voice interfaces)
- Power Modules:
- DC Module: (-48Vdc, -24Vdc, -125Vdc)
- Dual Power: (1+1) Protection
