    E&M – In this mode, the AVA-E interfaces to the tie trunk port of a PBX, and provides a Type 1 E&M signaling interface. This is a logic level type interface, where typically the PBX places battery voltage on the M-lead to indicate an off-hook condition to the AVA-E, and the AVA-E in return, places a ground on the E- lead to indicate a busy condition to the PBX.
  • Page 14: Internal Jumpers

    Internal Jumpers There are several internal jumpers in AVA-E. Only jumpers J4 and J6 are typically of interest to the AVA- E user. To access the jumpers, remove the two screws from the front panel and slide the enclosure cover forward about three inches.

    This can occur if the network is interrupted or if network end to end delays vary widely. When the jitter buffer underflows, the AVA-E has no new voice packets to send to the decoder, and the result is a glitch in the recovered audio. When an underflow is detected, the AVA-E will stop sending voice packets to the decoder until the jitter buffer again fills above the jitter level.
