MTP level 1 (64 kbit/s PCM time slot)
MTP functions
MTP level 1 (signalling data link level):
Physical transmission (e.g. 64 kbit/s PCM time slot)
MTP level 2 (signalling link level):
HDLC-type frame-based protocol for flow control, error control (using
ARQ), and signalling network supervision and maintenance functions.
MTP level 3 (signalling network level):
Routing in the signalling network (using OPC, DPC) between SPs with
level 4 users (see SIO at level 2).

Application protocols in SS7
TUP
(Telephone User Part) – is being replaced by ISUP
ISUP
(ISDN User Part) – for all signalling related to setting up,
maintaining, and releasing circuit switched connections
MAP
(Mobile User Part) – for transactions between exchanges (MSC,
GMSC) and databases (HLR, EIR, AuC) in mobile networks
INAP
(Intelligent Network Application Part) for IN applications in
fixed networks
CAP
(CAMEL Application Part) for extended IN functionality in
mobile networks (where MAP is not sufficient ...)
