The difference between an HSL MTP2 link and an Nx64/56kbps MTP2 link is that the Nx64/56kbps link uses many (N) independant timeslot, each containing an [[HDLC]] receiver/transmitter, grouped logically into a single MTP2 link. On the other hand, the HSL link is really a single [[HDLC]] receiver/transmitter that is not bound to a timeslot usual 7/8 bits boundary. It uses the complete trunk frame possible bandwidth to transmit data. An Nx64/56kbps link can be switched through a digital cross-connect equipment that handles the timeslot level (also referred to as &#039;channelized&#039;) while an HSL link cannot.<br /> <br /> [[category:Glossary]]</div>
