TXC-04228 - E1Mx28 Device DS1 Mapper 28-Channel
The T1Mx28 is a 28-channel byte-synchronous and asynchronous DS1 mapper.
Four field-proven DS1MX7 DS1 Mapper chips are interconnected in a single compact package to permit higher application board densities.
Both SONET and SDH mappings are provided per Bellcore GR253-CORE (VT1.5) and ITU G.707 3-96
