Known Software Limitations Part No. T0001-42, Rev C October, 2002 Page 56 of 103 3270 BSC Message Size Limitation - Vanguard 6400 Series An error may occur when 3270 BSC handles large message sizes. If a host sends a message that is larger then the 254 characters allowed in a block, when transmitted on the TPAD end, the first block ends with the End of Text Block (ETB). Once there is an acknowledgment received for the first block, the TPAD sends a End of Transmission (EOT) before sending the second block, which ends the message, and has the BSC controller write to the device. This causes an error in some applications as it expects the whole message in multiple blocks before the EOT. (DRFaa18075) Workaround: At present, there is no workaround. Vanguard 7300 Port Speed The "Port Speed:" field in the FRI, PPP, X25, SDLC, and TBOP statistics screen is the configured Port Speed for the Vanguard 7300 Serial Port. If the "Clock Source" parameter in the FRI, PPP, X25, SDLC, or TBOP serial port is set to EXT or EXTLP, the "Port Speed:" field in the FRI, PPP, X25, SDLC, and TBOP statistics screen may not match the speed of the actual clock on the serial line. (DRCaa21740) Workaround: To determine the actual speed on the serial line, an external datascope or protocol analyzer needs to be attached. The "Clock Speed" parameter in the Port Record needs to be configured to the actual Clock Speed that the port is attached to. Improper Configuration for LLC-SDLC-Stations - Vanguard 7300, Vanguard 6400 Series LLC-SDLC-Station Records in the Second Ethernet Station Table become the Records of the First Ethernet Station Table if the First Ethernet port record is deleted. (DRCaa21097) (DRCaa22325) Workaround: The first work around is not to delete the first Ethernet port. The second work around is to re-configure the LLC-SDLC-Station Records with the Ethernet port that has not been deleted. There is no SET_UP ACK generated for ISDN PRI Voice Calls with Overlap Sending - Vanguard 6400 and 7300 Series Overlap Sending/Receiving is not supported by North American switch types (DMS100, 5ESS, NI-2) (DRCaa22328) (DRCaa22105). Workaround: When configured for these switches, the attached device or switch must use Enblock mode only. Vanguard 7300 Series Call Not Transferred with ALT-Dest set in VST When placing a call from either an FXS, FXO or E&M to H.323 and the destination does not answer the phone (ALT_DEST_NO_ANSER) or the phone is busy (ALT_DEST) and the alternate destination is either an FXS, FXO or E&M, there is no audio. (DRCaa22329) Workaround: At present, there is no workaround. Vanguard 7300 Series Large QoS Parameter Values May Disable QoS Although the QoS Parameter fields can be configured to a maximum of 1000 or 10000 (in case of IP Flow Table Size), this is subject to the node's RAM availability. The software checks the node for sufficient RAM to accommodate a QoS parameter

3270 BSC Message Size Limitation - Vanguard 6400 Series
An error may occur when 3270 BSC handles large message sizes. If a host sends a
message that is larger then the 254 characters allowed in a block, when transmitted
on the TPAD end, the first block ends with the End of Text Block (ETB). Once there
is an acknowledgment received for the first block, the TPAD sends a End of
Transmission (EOT) before sending the second block, which ends the message, and
has the BSC controller write to the device. This causes an error in some applications
as it expects the whole message in multiple blocks before the EOT. (DRFaa18075)
Workaround:
At present, there is no workaround.
Vanguard 7300 Port Speed
The "Port Speed:" field in the FRI, PPP, X25, SDLC, and TBOP statistics screen is
the configured Port Speed for the Vanguard 7300 Serial Port. If the "Clock Source"
parameter in the FRI, PPP, X25, SDLC, or TBOP serial port is set to EXT or EXTLP,
the "Port Speed:" field in the FRI, PPP, X25, SDLC, and TBOP statistics screen may
not match the speed of the actual clock on the serial line. (DRCaa21740)
Workaround:
To determine the actual speed on the serial line, an external datascope
or protocol analyzer needs to be attached. The "Clock Speed" parameter in the Port
Record needs to be configured to the actual Clock Speed that the port is attached to.
Improper Configuration for LLC-SDLC-Stations - Vanguard 7300,
Vanguard 6400 Series
LLC-SDLC-Station Records in the Second Ethernet Station Table become the
Records of the First Ethernet Station Table if the First Ethernet port record is deleted.
(DRCaa21097) (DRCaa22325)
Workaround:
The first work around is not to delete the first Ethernet port. The sec-
ond work around is to re-configure the LLC-SDLC-Station Records with the Ether-
net port that has not been deleted.
There is no SET_UP ACK generated for ISDN PRI Voice Calls with
Overlap Sending - Vanguard 6400 and 7300 Series
Overlap Sending/Receiving is not supported by North American switch types
(DMS100, 5ESS, NI-2) (DRCaa22328) (DRCaa22105).
Workaround:
When configured for these switches, the attached device or switch
must use Enblock mode only.
Vanguard 7300 Series Call Not Transferred with ALT-Destset in VST
When placing a call from either an FXS, FXO or E&M to H.323 and the destination
does not answer the phone (ALT_DEST_NO_ANSER) or the phone is busy
(ALT_DEST) and the alternate destination is either an FXS, FXO or E&M, there is
no audio. (DRCaa22329)
Workaround:
At present, there is no workaround.
Vanguard 7300 Series Large QoS Parameter Values May Disable QoS
Although the QoS Parameter fields can be configured to a maximum of 1000 or
10000 (in case of IP Flow Table Size), this is subject to the node’s RAM availability.
The software checks the node for sufficient RAM to accommodate a QoS parameter
