E1/T1 PCI card installation guide
5
In most instances the functionality of both DSPs is the same. One exception however is when
using the DSP 65 for tone based CAS protocols. In this instance the following additional DSP
firmware file needs to be downloaded to the DSP65:
acasa.b65
for a-law
acasu.b65
for u-law
For all other functions, such as with tone detection, the file name suffix denotes the firmware file
to be used. For example:
cpdtmfu.bin
for u-law tone detection on a DSP32
cpdtmfu.b65
for u-law tone detection on a DSP65
See the Aculab Call switch and speech driver guide for further details on using the DSP
resources.
The
Card Installation & Connection
section refers to installation of the E1/T1 PCI card into a host
computer, hardware control and configuration information, and subsequent connection to the
network.
The
Approval Information
section, in conjunction with the country-specific appendices, gives the
conditions of the Approval for connection to the telephone network, requirements for installation
and safety, and other regulatory matters. This section and the appropriate country-specific
appendices contain statements regarding the use of the E1/T1 PCI card that are legal
requirements for connection to the public network. Failure to use the E1/T1 PCI card in
accordance with any of these instructions for use may invalidate the approval for connection.
Call and Switch control functions are provided via one of several device drivers that are
described in separate specific publications.
The card is not a complete product, and only has usable functionality when associated with a
host computer and an application program.
These instructions for use assume that these various elements are being assembled and
integrated by someone competent in such matters. Please contact Aculab support if you are
unsure of any issues arising from the use of the Aculab PCI card. Contact details may be found

Uses of the E1/T1 PCI card
The E1/T1 PCI card is a plug-in card suitable for use in many different types of PCI compatible
computer. Up to four E1/T1 primary rate ports are installed on a plug-in Line Interface Module
(LIM) providing a means of connection to a digital telephone network. The four port LIM is
referred to as the PM4 (Primary rate Module 4 port), the two port LIM is referred to as the PM2
and the single port LIM is referred to as the PM1.
The E1/T1 PCI card provides an ECTF H.100 CTBus port that allows interconnection with a very
wide range of third-party products. The E1/T1 PCI card contains a digital switch matrix that
allows arbitrarily switched interconnection between up to 120 channels on the E1-network or 92
channels on the T1-network or 4096 speech paths (timeslots or channels) on the H.100 CTBus.
Control of the E1/T1 PCI card is via a low-level interface ported to the PCI bus. The card is
essentially operating system independent, and may be used in a Windows NT/2000, Linux, or
indeed any other operating system environment using a suitable device driver. Please contact
Aculab plc for information on current device driver availability.
