Description
The MT90502 Multi-Channel AAL2 SAR bridges a
standard TDM (Time Division Multiplexed) backplane
to a standard ATM (Asynchronous Transfer Mode)
bus. The device provides the CPS (Common Part
Sublayer) and SAR (Segmentation and Reassembly)
engines.
The
MT90502
simultaneously processing 1023 bi-directional CIDs
(AAL2 Channel Identifiers) and bi-directional VCCs
(Virtual Channel Connections). The device can be
connected directly to an H.110 compatible bus. The
TDM bus consists of 32 bi-directional serial data
streams operating at 2.048, 4.096, or 8.192 Mbits/s.
has
the
capability
of
The MT90502 directly accepts PCM (Pulse Code
Modulation) and ADPCM (Adaptive Differential Pulse
Code Modulation) traffic for packetization. For the
G.711 and G.726 data formats, the device also
implements silence suppression and comfort noise
generation. To support other voice compression
algorithms,
the
MT90502
commercially available DSPs through synchronous
connects
directly
to
serial data streams. The Variable Bit Rate (VBR)
traffic is HDLC encapsulated and carried over the
serial data streams.
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. Ports A and B combined, architects a
compliant UTOPIA Level 2 Multi-PHY port. Port C is
UTOPIA Level 1 compliant. The MT90502 provides
the capability of routing ATM cells to different
UTOPIA interfaces, SAR engine or CPU. This feature
can be used to connect another MT90502 (to
support over 2000 phone calls) or to connect an
external AAL1 and AAL5 SAR.
