Known Problems and Workarounds
This section describes known problems and workarounds for version B.11.11.00 of the J2793B
X.25 product.
• Coexistence between the X.25 PSI cards and the ACC (Advanced Communication
Controller) cards on the same system is not supported.
You can use PSI cards supported by the J2793B product or ACC cards supported by
the Z7476AA product, but do not install both cards on the same system.
If the X.25/ACC Link software product is installed and even if not in use the PCI cards
cannot be used.
Coexistence between these products may be supported in a future release.
• If you are using modulo-128 with any of the following cards and you set Level 2 window
size to the maximum setting, you may experience periodic frame resets and
retransmission of packets because of memory allocation restrictions on these cards:
— J2792A HP-PB (NIO) 1-port card
— J2794A EISA 1-port card
— J3526A PCI 4-port card
Workaround. We recommend that you adjust the maximum Level 2 window size rangeto
the following values:
Table 1-1 Recommended Window Sizes
Level 3 Packet Size Level 2 Window Size

2048 1 - 60
