Protocol Architecture for MTP2 Tunneling
SS7 Characteristics
Only standard protocols are used on external interfaces (MTP2 on PSTN side, and
M2UA over SCTP on IP side) - the M2TN application resides internally in the V7122.
No extra signaling point codes are required; both endpoints are unaware that the SS7
connection is via IP.
Several links from multiple SS7 nodes can be concentrated into a single board on the
‘Central’ side (using several SCTP associations per gateway).
V7122 gateways can handle SS7 MTP2 tunneling and voice concurrently (does not
require additional gateway or other server).
Voice and signaling can be transferred on the same E1/T1 trunk (F-Links).
IP traffic can be monitored via standard sniffing tools (e.g. protocol analyzers).
Channels that are used for SS7 Tunneling mustn’t be defined in the Trunk Group
table.
SS7 Parameters
The parameters in
Table 70
configure all MTP attributes simultaneously. To set each MTP
attribute individually, add _xx (xx equals the element number in the range of 0 to 2) to the
end of the
ini
file field name.
