Description
The MT90500 Multi-Channel AAL1 SAR is a highly
integrated solution which allows systems based on a
telecom bus to be interfaced to ATM networks using
ATM Adaptation Layer 1 (AAL1), ATM Adaptation
Layer 5 (AAL5) and ATM Adaptation Layer 0 (AAL0).
The MT90500 can be connected directly to a ST-BUS
time
division
multiplexed
containing up to 1024 full duplex 64kbps channels.
Up to 1024 bi-directional ATM VC connections can
be simultaneously processed by the MT90500 AAL1
SAR device.
(TDM)
backplane
On the synchronous TDM bus side, the MT90500
device interfaces with sixteen bidirectional ST-BUS
serial links operating at 2.048, 4.096 or 8.192 Mbps.
TDM bus compatibility with MVIP-90, H-MVIP, and
SCSA interfaces is also provided.
On the ATM interface side, the MT90500 device
meets the ATM Forum standard UTOPIA Bus Level
1. This supports connection to a range of standard
physical layer (PHY) transceivers.
The MT90500 provides a built-in UTOPIA multiplexer
which allows external ATM cells to be multiplexed
with internally-generated cells in the transmit
direction. This feature can be used to connect
another MT90500 (to expand the TDM bandwidth of
the system to 4096 TDM channels), or to connect an
external AAL5 SAR (to multiplex non-CBR ATM cell
traffic with the MT90500 CBR stream).
