what's CRBT?
100K calls seems like lot of connections to the PSTN - especially for Asterisk
more detail please

use ss7 controlled trunks to the PSTN when PRI no longer makes sense
for technical, policy, or economic reasons
when using F link SS7 linksets to control IMT, they function very
similar to PRI trunks; when using A link linksets connected to STP,
then you can have a single linkset or combined links
end-of-pulse digit is 0xf (hex F, decimal 15, binary , bcd value
is not defined but '#' is used to represent it and causes decades of
confusion)

This idea has been batted around like a worn out cricket ball. It
seems like a great idea but no one ever does it.
Controlling AS5350 and other media gateways like it is usually done
using MGCP. Open protocol - seems cool. Seems like something like
Asterisk or ss7box could be the controller. In
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
ports an E1,

whew - i was choking on "SS7 on BRI"
typical in US/Canada is T1 or DS0A (inside the switch office only);
some other 56/64 interfaces are DSCS and V.35
http://en.wikipedia.org/wiki/DS0A
Asterisk users need only be concerned with T1, however

this is interesting; i've never known anyone who has seen this
actually working; can you describe how it was used
how did the end user use it? what was the bandwidth for? who was the
end user - a human or a machine?

if you have Sangoma cards you can use ss7box; SAM is working; clustering
working; it's a stable platform that runs ITU and ANSI; it's free,
unrestricted, and copyable now; until distribution and documentation are
set up to be autonomous, send me an email and I'll see that you get a copy
and I'll he

are those 2 "hosts" STPs or SSPs? what you describe could be a combined
linkset if connected to STPs and using ANSI SS7; if using ITU then this
might be a primary/alternate linkset scenario; my experience says the
combined linkset concept exists in ANSI SS7 and not in ITU

you are correct; the long-held suspicion is that the mgcp between the pw
and mg has proprietary extensions; using wireshark to sniff the protocol
would be the first step; would need cold start, warm start, and normal
operations captures; normal ops would contain lot's of normal and abnormal

connecting a mated pair of STPs to an ANSI network as a peer has more
requirements than connecting an SSP; ITU STP are less common so connection
requirements might be more variable

set? When I've seen things like this
in ITU networks, A was primary and B was alternate (used when A was not
available), instead of the ANSI model where A and B are peers and normally
used equally using a 5 bit SLS.

ITU and ANSI specs both support combined linksets; thought somebody posted
the howto 1-2 weeks ago

i can offer this bit of depressing information - at ss7box we never cracked
BT - we connected to other providers that had top-shelf equipment connected
to BT; BT has special features, connection testing is expensive, and
there's no fixing while testing - we figured that we'd need to buy a BT

is ss7 that interesting anymore? the landline subscriber base is dropping
steadily in the US - I assume this is happening elsewhere - so that puts
downward pressure on ss7 demand
