SDH – SONET Multiservice Access Multiplexer IMAP – O9500R

The Loop-O9500R SDH/SONET IMAP (Integrated Multi- Services Access Platform) is an economical STM-1/4/16 (OC- 3/12/48) access multiplexer designed to provide integrated access to STM-1/4/16 (OC-3/12/48) optical lines. Access is provided through either a non-blocking VC11/VC12/VC3/ VC4 cross-connect with HS tributary modules or through an additional non-blocking DS0 cross-connect fabric with LS tributary modules.

For access interfaces, 10+ low-speed modules are designed to encapsulate industry specific signals into DS0 timeslots. These interfaces include Voice (e.g. FXS, FXO, E&M, and etc.), Digital (e.g. RS232, RS449, X.21, and etc.), Teleprotection (e.g. G.703, C37.94) and so on.

For multiplexing and cross-connection, O9500R provides non-blocking cross-connection of up to 672 DS0 timeslots, which equal to 21 E1 channels, to serve as a MUX/DACS, and VC-n/VT-n fabric for SDH/SONET non-blocking cross-connection to serve as an ADM.

For transportation, high-speed modules provide transportation channels such as STM-1/4/16(OC-3/12/48) channels from Controller and B155/622 cards, Optical channels from 7-port FOM cards, E1/T1 channels from 63-port E1/T1 cards, and E3/T3 channels from 3-port E3/T3 cards.

For gateways, the signals from different interfaces can be freely encapsulated, cross-connected, and transported over a variety of transportation networks. For instance, E1/T1 and E3/T3 channels can be encapsulated into VT/VC paths and transported over SDH/SONET. Modules such as TDMoE and 8GESW make it possible for TDM traffic to be transported over Ethernet (DS0 over Ethernet) and the other way around (Ethernet over SDH/SONET) via circuit emulation and virtual concatenation technologies.
