Statistics

Card Number

This field indicates which (active) cards within the interface module the subsequent data fields reference. Each interface module will eventually be able to support up to eight (currently only one) T1/E1 Interface Cards, with only four cards active at any given time (See Cards Active below).

Pos Fslips

This field indicates the number of Positive Frame Slips accumulated at the CEC/IMC since the last Clear Stats command or the last TEC reset. A Positive Frame Slip occurs when a clocking frequency mismatch (at the card level) causes received frames to be repeated.

Neg Fslips

This field indicates the number of Negative Frame Slips accumulated at the CEC/IMC since the last Clear Stats command or the last TEC reset. A Negative Frame Slip occurs when a clocking frequency mismatch (at the card level) causes received frames to be discarded.

Con MemRes

This field indicates the number of Connection Memory Resets accumulated at the CEC/IMC since the last Clear Stats command or the last TEC reset. The Connection Memory stores input-to- output routing maps and thus controls the flow of audio and/or data signals on the T1/E1 Interface Card. A Connection Memory Reset will cause the TEC to issue a clock failure and be re-initialized by the Controller Board.

Sig Losses

This field indicates the number of "T1/E1 Interface-Loss of Signal" errors accumulated at the CEC/IMC since the last Clear Stats command or the last TEC reset.

Fsync Loss

This field indicates the number of "T1/E1 Interface-Loss of Frame Sync" error messages accumulated at the CEC/IMC since the last Clear Stats command or the last TEC reset.

Frmr Alarm

This field indicates the number of Framing Errors accumulated at the CEC/IMC since the last Clear Stats command or the last TEC
