Standard 1.0
Cannot access the Remote Gateway 911x series unit with an IP
interface (Q00764649)
The ARP table on the PC connected with a cross-connect cable does not time
out. It still associates the previous MAC address with the IP address. When the
Remote Gateway 911x series unit originates a PING, the table is updated with
the new MAC and all begins to function properly. This problem can be resolved
by entering an "arp -d" command on the PC to clear the ARP table.
Signaling link is lost on a normal closure over PSTN after a QoS
transition (Q00795922)
When you configure signaling for Permanent mode over IP and On-demand
mode over PSTN, the RLC generates an abnormal failure over PSTN after being
cleared normally due to an Idle condition detected. If after the QoS transition
occurs, additional B-channels are established, the problem does not occur.
Remote Gateway 9150 unit does not reconnect after a failed PSTN
test (Q00810610)
The following scenario describes the instance where the Remote Gateway 9150
unit is not reconnecting after a failed PSTN connectivity test:
Configure the RLC and Remote Gateway 9150 unit for PSTN only mode.
Perform a disruptive PSTN connectivity test. If the test fails, the Remote
Gateway 9150 unit stays in a state where it no longer attempts to connect when
the user presses a DN key to initiate a re-connection to the RLC.
To resolve this issue, re-set the Remote Gateway 9150 unit so that it can
reconnect to the RLC.
