CTA 500

The CTA 500 digital modem (CTA 500 dm ) is an optional device used with the Norstar Integrated Communication System (ICS). With ICS software, using release 2.0 or higher, the CTA 500 provides integrated desktop solutions for digital networking applications. With optional Norstar Telephony API Service Provider (TAPI SP), the CTA 500

also supports Computer Telephony Integration (CTI) services required for today's ofÞce environment. With the CTA 500

you can access remote computers on networks including the Internet. You can also telecommute over a digital telephone network and access the CTA 500 CTA 500

CTA 500dm

The CTA 500 dm serves as a digital modem and terminal adapter (TA). A terminal adapter is a device that allows non-ISDN devices to work with ISDN. It provides reliable high speed end-to-end digital connectivity between your computer and a remote data server using the ICS and the public switched telephone network (PSTN) or Integrated Services Digital Network (ISDN). The CTA 500 supports Point-to-Point Protocol (PPP) and Multilink PPP (MP), which are widely supported by Internet service providers (ISPs) for Internet access and corporate data communication networks (Intranets) for remote LAN access. PPP and MP are supported as built-in features of Windows95.

You can also connect a Norstar telephone to the CTA 500

to access Norstar voice services. You can use the same telephone line to simultaneously carry on a conversation while your computer is connected to the Internet or remote LAN with no loss of ICS features. The CTA 500

connects to the ICS using standard

telephone cabling.

MP works with intelligent bandwidth management software in the ICS to provide dynamic bandwidth allocation accessible at your desktop. Norstar station interfaces support two channels that are ßexibly allocated to transmit data, voice, or both. When the attached Norstar telephone is not in use, all bandwidth is allocated for data trafÞc (up to 128 kbit/s). However, if you want to use the phone to answer an incoming call, or place a call using the free line or the intercom, one channel is automatically allocated for the conversation and the data connection continues at 64 kbit/s. When you hang up the telephone, the second channel is automatically reallocated to the data connection.

Using a CTA 500 CTA 500

allows simultaneous PPP/MP data connections and

compliant Norstar TAPI Service Provider, the

TAPI computer telephony integration (CTI) applications on your PC.

CTA 500

In addition, some of the ICS resources normally used for voice applications, such as network access lines and calling line features, can be used for data trafÞc. Network access lines can be shared between CTA 500

s and other trafÞc within the system. Features such as call logging, call restriction, and routing based on time of day can be applied to data trafÞc for facility utilization and management.

Applications

CTA 500dm 3

Any PC equipped with Windows95, Internet application software, and a 16550 UART (115.2 kbit/s capability) can use the CTA 500

The CTA 500 dm can be used for any application that requires dial-up capability and uses Point-to-Point Protocol.

These applications include

¥ Internet access

¥ remote LAN access

¥ high-speed modem replacement

¥ CTI based applications when Norstar TAPI SP is added

¥ data transmission at up to 64 kbit/s on either channel of an ISDN

link or 56 kbit/s on a T1 trunk

¥ supports Multilink PPP to enable the dial-up connections to use

two channels

Internet access

The CTA 500 dm allows Norstar customers using digital network interfaces on the Norstar ICS to access Internet service providers (ISPs). You can connect an ISP through the public switched digital network (PSDN) using regular dial-up methods.

Dial-Up Networking

You can use the CTA 500 dm for remote LAN access applications when PPP is used to connect to a remote LAN.

Data-to-data transfers

The CTA 500 dm can be used to establish a connection with an ISDN Terminal Adapter (PPP or MP must be supported) or another CTA 500 same ICS through their own CTA 500 through the network. Using the CTA 500

for Þle transfer. You can connect two computers to the

units, or connect them

connection allows analog modems to be replaced with high-speed digital connections. The CTA 500

does not support connection to analog or 56k

modems.

Computer Telephony Integration (CTI)

With a compliant Norstar TAPI SP, the CTA 500 dm allows simultaneous sessions of PPP/MP and CTI based applications to run on PCs.

Setting up the ICS

Program the ICS for the CTA 500dm the same way that you program the ICS for a Norstar set. You can program line access, line pool codes and restrictions to apply to outgoing calls. The CTA 500dm must be assigned to a digital line or to a digital line pool. Refer to the ÒTerminals and sets programmingÓ section of your Installer Guide for more information.

The CTA 500dm is a B2 channel device and must be assigned a B2 channel DN. The following table shows the default directory number (DN) that is assigned to the CTA 500dm based on the physical set port that connects the CTA 500dm to the ICS.

Installing Norstar TAPI SP

To use a CTA 500dm for TAPI applications, Norstar TSP must be installed. It can be installed at the same time as the CTA 500dm software via the Personal Productivity Suite (PPS) installation procedure, or it can be installed later from the PPS CD.

Note: The current CTA 500dm conÞguration does not support

dynamic bandwidth allocation if you donÕt have access to a line pool with more than two ISDN lines. When you are making an MP data call and want to make a voice call at the same time, lift the telephone handset in order to make a channel available for the call.

Conﬁgure TAPI dialing properties

If you use an access code to get an external line or get a private network line to make a long distance call (for example, dial 9 before dialing an external number or dial 6 before dialing a long distance number), you need to conÞgure the Norstar set attached to the CTA 500dm.

1. Click the Start button and move the cursor to Settings.

2. Choose Control Panel from the sub-menu.

3. When the Control Panel window displays, double-click the
