Description
The Zarlink MH88634CV-K Central Office Interface
Circuit trunk provides a complete analog and signalling
link between audio switching equipment and a
telephone line.
The device is fabricated as a thick film hybrid
incorporating various technologies for optimum circuit
design and very high reliability.
The component design has been changed to improve
the general performance of the part. It is also now
capable of operating at a 24V battery and on hook
reception.
The main difference between the MH88634BV-2 and
MH88634CV-K is that SHK is active high on the CV-K.
