Description

The ZL50031 Digital Switch provides switching

capacities of 4,096 x 2,048 channels between

backplane and local streams, 2,048 x 2,048 channels

among local streams and 2,048 x 2,048 channels

among backplane streams. The local connected serial

inputs and outputs have 32, 64 and 128 64 kbps

channels per frame with data rates of 2.048, 4.096 and

8.192 Mbps respectively. The backplane connected

serial inputs and outputs have 128 and 256 64 kbps

channels per frame with data rates of 8.192 and

16.384 Mbps respectively.

Connection memory block-programming for fast

device initialization

Pseudo-Random Binary Sequence (PRBS) pattern

generation and testing for backplane and local

streams

Conforms to the mandatory requirements of the

IEEE-1149.1 (JTAG) standard

3.3 V operation with 5 V tolerant inputs and I/O’s

5 V tolerant PCI driver on CT-Bus I/O’s

Carrier-grade VoIP Gateways

IP-PBX and PABX

Intregrated Access Devices

Access Servers

CTI Applications/CompactPCI

Applications

H.110, H.100, ST-BUS and proprietary Backplane
