The most common form of E1 signalling in Mexico is E1R2 whgich uses MF tones, while the US would probably be E&M wink using DTMF tones.
T1 CAS uses timeslots 6,12, 18 and 24 to pass the ABCD bits via robbed bit signalling. E1 CAS uses timeslot 16 to pass the ABCD bits.
E&M uses the state of idle and sieze, while E1R2 uses the states seize, seize ack, answer, clear bwd, clear fwd and idle.
There is no way for the D&I function to firstly convert between the robbed bits of the T1 to the single dedicated channel of the E1. Secondly the call states and bit patterns are different between E&M and E1R2.
There is no way this is going to work with Drop and Insert... The only way to do this is to put voice cards and DSP's at each site and interpret the signalling locally and switch the calls as VOIP across the data link.
The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
