2 CTA 500dm

The CTA 500dm 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 500dm 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 500dm 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 500dm 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 500dm compliant Norstar TAPI Service Provider, the

CTA 500dm allows simultaneous PPP/MP data connections and

TAPI computer telephony integration (CTI) applications on your

PC.

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 500dms 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.
