Limitations
•
The total number of 4-Port and 1-port Multi-protocol Serial I/O Adapters can not be more than the
maximum supported by the Escala model.
•
The 4-Port Multi-protocol Serial I/O Adapter cannot be plugged in the first and the last PCI slot of
Escala T Series models.
•
The 4-Port Multi-protocol Serial I/O Adapter cannot be plugged in the last PCI slot (#5) of the
Escala S Series models.
3.4. 1-Port Multi-protocol Serial I/O Adapter (DCCG097)
The
1-Port Multi-protocol Serial I/O Adapter
is an entry level SDLC and X.25 adapter which
provides a powerful X.25 and SDLC offer at a very competitive pricing. It consists of a card that
supports either one V.24 or V.35 or V.11/X.21 physical interface. This physical interface type is
software selectable.
The
1-Port Multi-protocol Serial I/O Adapter
is fully integrated in the Bull communication offer:
•
TCP/IP, SNA/20
(Valid on Escala E & T only),
HVX, XTI, XX25
and
OSI
applications run and
have access to X.25 networks through this adapter. This board can support up to 1024 virtual
circuits according to stacks capabilities.
•
SNA/20
applications run and have access to SDLC networks through this adapter (Escala E & T
only)
The adapter can support up to 200 frames/sec (with frame size = 128 Bytes) according to stacks
capabilities.
Hardware
•
PCI short card, 1 slot used
•
NET2 conformance
•
Maximum line speed:
V24: 28.8 Kbps
V.35: 64 Kbps
V.11/X.21: 128 Kbps
•
1 HDLC communication controller (ZILOG IUSC) available on the card. It is customized with one
of the following interfaces: V.24, V.35 and V.11/X.21.
Cables
The board provides a 25 points female connector that could be connected to appropriate cables
providing different types of interfaces. The cables are same as for 4-Port Multi-protocol Serial I/O
Adapter and are listed hereafter:
•
V.24 cable: up to 28.8 Kbps (10m)
•
V.35 cable: up to 64 Kbps (10m)
•
V.11/X.21 cables: up to 128Kbps (10m).
