[asterisk-ss7] SS7 + T1 on Asterisk?

if one slot out of 48 is for an SS7 link, then this configuration is
called an 'F' link - it is a single link linkset

if asking about T1 then chances are good that you are in an ANSI world
- the ANSI world connects to the SS7 net via mated pair STPs - your
node needs at least 2 dedicated T1 using one slot in each, with each
T1 connecting to one of the mated pair STPs; a third T1 carries voice;
kind of expensive for a single T1

sometimes you can get a T1/ANSI F link linkset to a switch on the edge
of the network but you are not a network peer when you do that - and
being a network peer is one of the reasons to use SS7; sometimes this
is done to learn about SS7 connectivity

E1/ITU F links are common and allow you to be a network peer

make sure you have a strong case for doing this
