TruePulse is looking to purchase Lucent TN1625 boards for the 5ESS. The board may also be branded as AT&T, Alcatel-Lucent or Nokia.
The TN1625, HECI code DSPQAC4, is a DCSS 2W Line Control card for the 5ESS.
The Lucent 5ESS Switch is a Class 5 telephone Electronic Switching System (ESS). It supports different applications that can be configured to coexist with each other thereby allowing operators to implement multiple applications more cost-effectively on just one switch instead of multiple switches. The same 5ESS Switch can simultaneously support Wireless, Local-Toll, Intelligent Network (IN), and Gateway Exchange applications.
