- I realize that comp.dcom.telecom is not the right place to post
- press releases, but for some reason I don't seem to have access to
- the "newprod" group, and a lot of folks have been asking about ISDN
- cards for AT-bus machines. So... attached is a recent press release
- from Hayes regarding our ISDN PC Adapter.

-
- Hayes ISDN PC Adapter
-
- The Hayes ISDN PC Adapter implements the CCITT ISDN Basic Rate Interface
- (2B+D) supporting simultaneous voice and data communications. This
- internal terminal adapter is designed for the installed base of IBM PC XT,
- AT and compatible personal computers. Specific ISDN features include
- support of Northern Telecom DMS 100 and AT&T 5ESS central office switches,
- CCITT X.25, ANSI V.120, high speed data rates for circuit switched and
- packet switched data, as well as comprehensive ISDN voice services.
-
- ISDN SERVICES (Basic Rate Access)
-
- Data Capabilities - Circuit switched data connection on a B channel can
- transmit at high speeds using either X.25 or V.120 protocols for rate
- adaption flow control, and error control. Packet switched data (which
- uses X.25) can be provisioned on a B Channel with up to 8 sessions.
- Packet switched data provisioned on the D Channel can also support up to 8
- sessions. The actual total number of data sessions is dependent on the PC
- system memory available.
-
- Voice Capabilities - Circuit switched voice communications is available
- on one of the B channels using an analog phone attached to the RJ-11
- connector on the adapter's back bracket. An external power supply is also
- included to provide voice communications even when the PC is powered off.
-
- The supported ISDN voice services include Basic Call Control; Flexible
- Call Offering - Conference, Drop, Transfer, Hold, Retrieve; Incoming and
- Outgoing Calling Line Identification; Feature Button Support for
- Supplementary Services; two call appearances, and in-band B channel Dual
- Tone Multiple Frequency (DTMF) signalling. Speed calling, call
- forwarding, call park, call pickup are examples of the Supplementary
- Services the ISDN PC Adapter supports. The exact options of the Feature
- Buttons supported are switch dependent.
-
- SUPPORTED SERVICE OPTIONS
-
- Combinations of these services are dependent on the switch's line
- provisioning.
-
- SWITCH/NETWORK COMPATIBILITY
-
- Switch Support - The Hayes ISDN PC Adapter System Software is the
- executable code that is uploaded to the adapter's on-board RAM by the PC
- at initialization. This flexibility provides an easy product upgrade path
- to address changes in standards and future enhancements.
-
- The ISDN PC Adapter system will be certified with the AT&T 5ESS Generic
- SE5, and the Northern Telecom DMS 100 BCS 29.
-
- Hayes will continue to develop System Software that will support
- additional switches and switch enhancements as the markets develop and
- these features become widely available to the general public.
-
- Network Support - Supports 64K Unrestricted or 64K rate adapted from 56K
- network transmission.
-
- ISDN STANDARDS SUPPORT
-
- Hayes supports Northern Telecom DMS 100 and AT&T 5ESS implementations of
- CCITT Q.931/I.451 which provides signaling and call control, and CCITT
- Q.921/I.441 which implements the specified Data Link Layer and provides
- error control. The Hayes ISDN PC Adapter also supports the CCITT I.430
- network interface, and ANSI V.120 and CCITT X.25 for rate adaption and
- flow control. CCITT X.3 and X.29 are implemented for X.25 packet switched
- data on the B or D channel. X.28 functionality is provided through the
- Hayes Standard AT Command Set Enhanced for ISDN and ISDNBIOS.
-
- INTERFACES
-
- Analog Telephone Interface - Analog telephone interface is provided via
- an RJ-11 connector on the ISDN PC Adapter's back bracket. The adapter
- provides ring equivalence to support up to three 2500-type compatible
- analog devices such as telephones, modems, and Group III facsimile
- machines through the single RJ-11 connector.
-
- ISDN Line Interface - An RJ-45 connector on the back bracket is the
- physical interface for the ISDN Basic Rate S/T interface.
-
- PC Host Interface - There are two separate software interfaces to the
- Hayes PC Adapter. The adapter supports a serial data interface, like a
- modem, accessed via a COM port; and high speed data transfers are
- performed via shared PC memory using the Hayes ISDNBIOS Interface. Voice
- and data calls can be monitored and controlled through either of these
- interfaces.
-
- TRANSMISSION MODES
-
- When using the Hayes Standard AT Command Set Enhanced for ISDN, the
- following asynchronous character formats are supported in the adapter
- according to the following speeds and protocols:
- Data Formats:
- 7 data bits and 1 parity bit (even, odd, mark, or space),
- 8 data bits with no parity, and
- 1, 1.5, or 2 stop bits in the DTE-to-DCE direction, or
- 1 stop bit in the DCE-to-DTE direction.
- DTE Serial Interface Speeds supported:
- 300, 1200, 2400, 4800, 9600, 19200, 38400 bits per second.
-
- Through the Hayes ISDNBIOS Interface, the ISDN PC Adapter supports actual
- data transfers of over 50,000 bps. Rate adaption protocols are used to
- guarantee flow-controlled, in-sequence, unduplicated, and error controlled
- delivery of data.
-
- CONTROL AND OPERATION
-
- Hayes Standard AT Command Set Enhanced for ISDN - One of the PCA's
- Application Programming Interfaces (APIs) is the Hayes Standard AT Command
- Set Enhanced for ISDN. This API provides autobauding at up to 38.4Kbps
- and allows the PCA to provide high speed data services while emulating a
- Hayes Smartmodem. Voice call control and monitoring as well as multiple
- data calls on the 2B and D channels are available through this API. The
- available call types include PSD-D X.25, PSD-B X.25, V.120, and voice.
-
- Hayes ISDNBIOS Interface - To support the high data rates and access the
- multi-session capabilities of ISDN, Hayes has developed the Hayes ISDNBIOS
- Interface which provides an enhanced mode of operation. Through this
- interface, based architecturally on IBM NETBIOS, users can achieve actual
- data transfer rates of over 50,000 bps. This interface allows multiple
- applications operating in foreground or background to use the Hayes ISDN
- PC Adapter simultaneously, and is well suited for access by Terminate and
- Stay Resident (TSR) programs. The Hayes ISDNBIOS Interface is also the
- preferred interface for development of wide area networking (WAN)
- applications.
-
- Flow Control - When using the serial port, flow control between the
- terminal and terminal adapter is determined via AT commands.
-
- Flow control is inherent in the Hayes ISDNBIOS Interface and is handled
- automatically.
-
- Non-Volatile Memory - Non-volatile memory is provided to store
- configuration parameters. Once the Hayes ISDN PC Adapter has been
- configured for the line, it will remember this custom configuration even
- if the adapter is powered off or reset.
-
- CONFIGURATION AND DIAGNOSTICS
-
- An installation program helps the user identify their PC system
- configuration and install the Hayes ISDN PC Adapter with the appropriate
- System Software. Configuration of the PCA is made easy by the
- user-friendly Configuration Program and thorough documentation included
- with the PCA.
-
- OPERATING ENVIRONMENT
-
- The Hayes ISDN PC Adapter is for use with IBM PC XT, AT or 100%
- compatible personal computers. The system needs DOS 3.1, 3.2, or 3.3
- version, a hard disk with at least 1.5M bytes available, and 640K bytes of
- system memory is recommended.
