Description
The MT90503 is an AAL1 SAR, which offers a highly integrated solution for interfacing telecom bus-based systems
with ATM networks. The device has the capability of simultaneously processing 2048 bidirectional channels of 64
kbps. The MT90503 can be connected directly to an H.100 or H.110 compatible bus. The device also offers the
capability of using Channel Associated Signalling (CAS) to support Circuit Emulation Service (CES) for Structured
Data Transfer (SDT).
The interface to the TDM port is provided by a TDM bus, which consists of 32 bidirectional serial TDM data streams
at 2.048, 4.096, or 8.192 Mbps, therefore allowing for 2048 bidirectional TDM channels operating at 64 kbps. This
TDM bus is compatible with the ECTF H.100 and H.110 specifications.
The interface to the ATM domain is provided by three UTOPIA ports (Ports A, B, and C). All three of the UTOPIA
ports can operate in ATM (master) or PHY (slave) mode. Port A can also be configured as Level 2 M-PHY mode.
