Multichannel communications controllers
Due to changing standards requirements and market dynamics, Texas Instruments has decided to discontinue development and productization of TNETC2040 and TNETC2080.
The TNETC2040, a multichannel controller for use with T1/E1 lines, combined four high-level datalink control (HDLC) processors onto a single chip. To be used in applications such as SOHO routers and access concentrators, the TNETC2040 was designed offer up to 32 channelized data streams. Changes in customer requirements late in the design cycle have created a time-to-market issue, forcing Texas Instruments to re-evaluate the viability of this part.
The TNETC2080, a multi-channel controller for use with high data throughput serial lines, offered eight programmable, full-duplex, frame-based un-channelized interface ports. Recent changes in broadband communications standards indicate that applications such as DSLAMS, access servers and concentrators for ADSL will use a cell-based protocol, rather than frame-based. Continued development of this product would not be standards based nor meet the needs of our customers.
Customers can obtain multi-channel controllers from either PMC Sierra or Seimans.
Texas Instruments will focus its efforts on developing ADSL solutions which expand the deployment of ADSL and meet our customers needs at both ends of the wire.
