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.
