New Tokens
The SS7_Q761_TG_PROFILE table will be modified to add a new optional token, EXCHANGE_TYPE.
EXCHANGE_TYPE
|
Signaling origination and destination local exchange type; A=an end to end exchange and B=an exchange that acts as a transit node. CHAR(1). 1=A, 2=B; 0=NULL (default). If the value of EXCHANGE_TYPE is not specified or specified to be NULL, the value defined in CA-CONFIG will be used.
