Table 78: Summary of Key PPPoE Output Fields (continued)
Field Values
PADI Resend Initial time, (in seconds) the Services Router waits
Timeout to receive a PADO packet for the PADI packet
sent—for example,
doubles for each successive PADI packet sent.
PADR Resend Initial time (in seconds) the Services Router waits
Timeout to receive a PADS packet for the PADR packet
sent. This timeout doubles for each successive
PADR packet sent.
Maximum Resend Maximum value (in seconds) that the PADI or
Timeout PADR resend timer can accept—for example, 64
seconds. The maximum value is
Maximum Time (in seconds), within which the configured
Configured AC access concentrator must respond.

Monitoring the TGM550 Media Gateway (VoIP)

J4350 and J6350 Services Routers support voice over IP (VoIP) routing through an
Avaya TGM550 Telephony Gateway Module and one or more Telephony Interface
Modules (TIMs) installed in the router. From the J-Web interface or the JUNOS CLI,
you can monitor the
Interfaces" on page 113). In addition, you can monitor dynamic call admission control
(CAC) operation, if it is configured on the router WAN interfaces, and also the list of
Media Gateway Controllers (MGCs) configured on the TGM550.
To display TGM550 information, select Monitor>Media Gateway in the J-Web
interface.

Additional Information
The PPPoE Active Discovery Initiation (PADI) packet
is sent to the access concentrator to initiate a PPPoE
session. Typically, the access concentrator responds
to a PADI packet with a PPPoE Active Discovery
Offer (PADO) packet. If the access concentrator does
not send a PADO packet, the Services Router sends
the PADI packet again after timeout period is
elapsed. The PADI Resend Timeout doubles for each
successive PADI packet sent. For example, if the
PADI Resend Timeout is 2 seconds, the second PADI
packet is sent after 2 seconds, the third after
seconds, the fourth after seconds, and so on.
8
The PPPoE Active Discovery Request (PADR) packet
is sent to the access concentrator in response to a
PADO packet, and to obtain the PPPoE session ID.
Typically, the access concentrator responds to a
PADR packet with a PPPoE Active Discovery
Session-Confirmation (PADS) packet, which contains
the session ID. If the access concentrator does not
send a PADS packet, the Services Router sends the
PADR packet again after the PADR Resend Timeout
period is elapsed. The PADR Resend Timeout
doubles for each successive PADR packet sent.
