Zl50023
Enhanced 4 K Channel TDM Switch with rate conversion
Overview
The ZL50023 is an enhanced non-blocking TDM switch with 4096 x 4096 channel switching capacity. The device offers per-stream rate selection and conversion, embedded G.711 (A-Law/u-Law) code conversion and simultaneous all-stream Bit Error Rate (BER) testing. It is designed to deliver performance advantages and cost benefits for low-density applications. |
