The communications D     controllers support DMA transfers for bit oriented protocols andH     perform character transmission, reception, and framing in microcode.  D  o  The DSW21 and DSW41 (single line) and DSW42 (dual line) are highF     performance synchronous communications controllers for busless Mi-D     croVAX 3100 and VAXstation 4000 systems. The communications con-F     trollers support DMA transfers for bit oriented protocols and per-E     form character transmission, reception, and framing in microcode.   D  o  The DMV11 (Q-bus) is a single line communications controller forF     Q-bus systems. The DMV11 implements DDCMP in firmware and supportsI     DMA data transfers and DDCMP point-to-point configurations. The DMV11 D     can support up to 12 tributaries depending on the operating sys-     tem and layered software.   D  o  The DPV11-DA or DPV11-S (Q-bus) and DUP11 (UNIBUS) are characterD     interrupt devices for datalink handling. CPU cycles are requiredG     for data link-level protocol processing and for each character sent      and received.   F  o  The DSV11 (Q-bus) is a high performance dual line synchronous com-G     munications device for Q-bus systems. The DSV11 supports DMA trans- E     fers for bit and character oriented protocols. The communications D     controller performs character transmission, reception, and fram-     ing in microcode.   F  o  The KMV1A-A or KMV1A-SF (Q-bus) communications controller executesG     transmission, reception, and X.25 LAPB link-level protocol process- E     ing in microcode. Optional link-level software products, drivers, G     and tools are available for the KMV1A device if required. The KMV1A /     device was previously known as the KMV11-A.   F  o  The DSF32 (MI-bus) is a multi-function device for VAXft fault tol-F     erant systems. The DSF32 provides a dual line synchronous capabil-F     ity and supports DMA transfers for bit and character oriented pro-F     tocols. The communications controller performs character transmis-H     sion, reception, and framing in microcode. The two lines can be usedF     independently to run different protocols or can be used to provide  #                                   2        F     a failover capability between lines in the event of an application     or system failure.  D  o  The DMB32 (BI-bus) and DMF32 (UNIBUS) are multi-function devicesG     that include a single DMA line. The communications controllers per- E     form character transmission, reception, and framing in microcode.   F     For the DMB32, revision J is required for applications using HDLC,E     SDLC, and GENBYTE protocols. In the case of the DMF32, only revi- F     sion J and later are supported for use with the HDLC protocol, andD     revision M is required for simultaneous operation of the printer	     port.   G  o  The DSB32 (BI-bus) is a high performance dual line synchronous com- G     munications device for VAXBI systems. The DSB32 supports DMA trans- E     fers for bit and character oriented protocols. The communications D     controller performs character transmission, reception, and fram-     ing in microcode.   D  o  The DMC11 and DMR11 (UNIBUS) are single line communications con-D     trollers that provide local or remote connections between UNIBUSE     systems. The DMC11 and DMR11 implement DDCMP in firmware and sup- D     port DMA data transfers and DDCMP point-to-point configurations.  H  o  The KMS1P-A, KMS1P-B, and KMS11-B (UNIBUS) products are DMA devices.F     The KMS communications controller executes character transmission,H     reception, and X.25 data link-level protocol processing in microcodeD     (LAPB only, for packets not larger than 1024 bytes). The VAX CPUF     then processes the X.25 packet level protocol. Optional link-levelE     software products and tools available for the KMS devices are not I     required. The KMS1P-A and KMS1P-B were previously known as the KMS11-      PX and KMS11-PY.    Notes:   E  o  The use of UNIBUS options on a VAXBI system with a UNIBUS Adapter G     is not supported unless specified in Table 2 of this Software Prod-      uct Description.    #                                   3        D  o  The DMB32, DMF32, and DSH32 are multi-function devices. Only theG     Device Driver for the synchronous ports are included in the VAX WAN      Device Drivers.   E  o  The DMB32 must be revision J or later for applications using GEN- "     BYTE, HDLC, or SDLC protocols.  E  o  The DMF32 must be revision J or later for applications using HDLC 
     protocol.   E  VAX WAN Device Drivers includes Device Drivers that are reserved for D  use by Digital software products as well as Device Drivers that of-E  fer a supported user ($QIO) interface. Table 1 of the System Support G  Addendum (SSA 29.64.03-x) lists the Device Driver characteristics. The E  table entries indicate the maximum permitted line speeds in kilobits G  /second for each of the protocols supported by the individual drivers.   F  The Device Drivers all support full duplex and half duplex operation,F  where appropriate to the protocol. DDCMP and SDLC Device Drivers sup-H  port both point-to-point and multipoint tributary operation. The IBM[R]E  implementation of the bisynchronous protocol is supported by some of G  the Device Drivers. The GENBYTE protocol, a general byte-oriented pro- F  tocol for use with user-written framing routines, is supported by the   DMB32 and DMF32 Device Drivers.  E  The maximum permitted line speed depends on the line interface stan- E  dard used and should not exceed the specification of the appropriate E  standard. Refer to the product descriptions for the appropriate syn- D  chronous interfaces for more information about the line speeds sup-   ported by an individual device.  E  Note: Digital communications layered products may not support opera- D  tion of the synchronous interface at the maximum speed supported byF  the Device Driver. Refer to the appropriate Software Product Descrip-H  tion for the Digital communications product for precise details of sup-  ported configurations.   D  In all cases, the data throughput over the synchronous lines is de-9  pendent on the user applications and system environment.   #                                   4        E  The device drivers all support modem control signal operation. Refer F  to the product descriptions for the appropriate synchronous interfaceD  for details of the modem signals supported by an individual device.    HARDWARE REQUIREMENTS  E  Processors and/or hardware configurations as specified in the System #  Support Addendum (SSA 29.64.03-x).     SOFTWARE REQUIREMENTS    o  VMS Operating System  E  Refer to the System Support Addendum (SSA 29.64.03-x) for availabil- =  ity and required versions of prerequisite/optional software.     ORDERING INFORMATION     Software Licenses: QL-VAWA*-**   Software Media: QA-VAWA*-**$  Software Documentation: QA-VAWAA-GZ'  Software Product Services: QT-VAWA*-**   G  *  Denotes variant fields.
