mpanl Sig Protocol Errors

This attribute counts the number of times a Q.933 protocol error has occurred. Any one of the following events constitutes a protocol error: 1. In the user-signaled Link Layer Core Parameters IE within the SETUP or CONNECT messages, Cir, Bc and Be are all zero; 2. In the user-signaled Link Layer Core Parameters IE within the SETUP or CONNECT messages, Cir is zero but Bc is non-zero, or Bc is zero but Cir is non-zero; 3. In the user-signaled Link Layer Core Parameters IE within the SETUP or CONNECT messages, the minimum acceptable Cir is greater than Cir; 4. At the destination end, any of the destination to source direction link layer core parameters has been increased in the CONNECT message from the called user; 5. At the destination end, the destination to source direction Cir in the CONNECT message is smaller than the corresponding minimum acceptable Cir signaled to the called user; 6. At the source end, any of the source to destination direction link layer core parameters in the CONNECT message from the destination end has been increased; 7. At the source end, the source to destination direction Cir, after negotiation, is smaller than the corresponding minimum acceptable Cir; 8. The network has received a STATUS message from the user with an incompatible Q.933 state. When this count reaches maximum, it wraps to zero.
