Bearer channels and one full duplex Delta channel combined onto a single pair of wire. The Teltone ILS-1000 (ISDN Line Simulator) is two ISDN BRI connections in a portable housing. The user interface is either a “U” or an “S/T” connection using an RJ45 modular plug. -

Page 7: Chapter 1: Quick Start
Chapter 1: Quick Start The ILS-1000 Line Simulator is easier to operate than most communications devices designed for ISDN-BRI applications. It functions in the background, providing two lines of end-to-end ISDN-BRI service. Because the Simulator was designed primarily for people who demonstrate, func- tionally test, or configure ISDN-BRI devices, you do not need to understand ISDN protocols or read the entire User’s Manual to use it. - Page 8 Step 6 After the Simulator’s provisioning is established, press RESTART. The settings are retained in non-volatile memory until you change them. You now have two ISDN-BRI telephone lines ready to provide Circuit Mode Voice (Speech, 3.1 kHz Audio, 7 kHz Audio), and/or Circuit Mode Data (56 Kbs Restricted, 64 Kbs Clear) services on two B Channels.

Another limitation occurs when attempting to place a call to a device that does not support the requested call type. For example, a call placed from an ISDN data terminal to an ISDN voice telephone will be rejected by the telephone. In some cases, the call type and number of channels are satisfied and the called device answers the call, but the calling application is not compatible with the called application. -

Layer 3, or the network layer, is a flexible switching and signaling language referred to as ISDN Call Control . The ILS-1000 is configured to support the first three layers of the OSI model. ISDN services are referred to as Call Types . Common call types are Circuit Mode Voice (CMV), Circuit Mode Data (CMD), and Packet Mode Data (PMD). -
Page 13: Layer 2 - Data Link Operation
Network Termination-1 (NT-1) The U Interface terminates at a device called a Network Termination-1 , or NT-1. This device converts the U Interface to an S/T Interface. It also permits loop back and testing by the telephone company and a means of routing local power to devices previously designed to receive power from the line, such as a telephone. -
Page 14: Layer 3 - Network Operation
TEI Assignment Most ISDN Terminating Equipment support a feature called automatic TEI assign- ment. After a device is connected and synchronized, packets are exchanged with the switch to establish the TEI. The switch knows which TEI’s are assigned to that line and can query each device if in doubt. - Page 15 Service Profile ID (SPID) Assignment Normally, each telephone line is assigned a single Directory Number. When a customer orders services or features, they are programmed into a Service Profile stored at the switch. Any call associated with that line can be assumed to apply only to that customer’s Directory Number and Service Profile.

STEP 1 Run the Windows based configuration software. STEP 2 Select the SWITCH TYPE STEP 3 Select DEFAULTS . - Page 19 The ILS-1000 Line Simulator supports a single channel for a Semi-Permanent or Permanent Virtual Circuit connection between Port 1 and Port 2. To demonstrate these services, STEP 1 Run the Windows based configuration software.

Page 21: Terminal Display Text
Terminal Display Text Many ISDN-BRI telephones, terminal adapters, and computer applications support a display feature that accepts and shows formatted ASCII text delivered by the network. The text may indicate an invoked feature or explain an error. Usually the text indicates the name and Directory Number of the called or calling party. If the Terminal uses Call Appearances, the Call Appearance identifier is also displayed for the current call. -

quent SETUP messages sent to that line may then address all, some, or only one device using the TEI. If the communications device does not store a TEI, then the Simulator’s EKTS setting should be disabled. STEP 1 Run the Windows based configuration software. STEP 2 Select the EKTS setting. -

However, a simpler method uses the Call Appearance Information Element. With this technique, the switch manages outgoing Call Appearance numbers and assigns incoming Call Appearance numbers. The Simulator manages a maximum of 15 Call Appearances per terminal, which is the default setting. To change the Call Appearance Call Handling setting, STEP 1 Run the Windows based configuration software. -

Note: This setting is not available when EKTS is disabled. While the Simula- tor recognizes the CONFerence and TRANSfer call control messages, it does not perform these services at this time. The ILS-1000 returns a reject mes- sage, as if the service was not subscribed. -
Page 25: Chapter 4: Simulator Operation
Chapter 4: Simulator Operation This section refers to the operation of the ILS-1000 in more detail. Many users of the Simulator will not need to read this section. When power is first applied to the Simulator, a self-test is performed and the inter- faces are initialized. -
Page 26: Restart
However, some terminals are designed to report link failures to their Call Control Layer, which may then attempt to recover. If their recovery procedure is not satisfied before various timers expire, they may clear (or dump) any active calls. Some terminals do not attempt to recover from data link failures, but simply termi- nate operation. -
Page 27: Chapter 5: Reference
Chapter 5: Reference Status Indications Figure 2 shows the ILS-1000 ISDN Line Simulator configured for U Interface opera- tion. Connecting to the U Interface allows synchronization of any communications devices connected downstream. The Simulator’s U interface status is signalled by the U-SYNC LED which changes from a blinking green LED to a solid green LED after synchronization has competed. -

Supported Call Control Messages The Simulator supports the ISDN-BRI Call Control messages listed below. For specification documents that describe the function of each message, see the end of this section.

Page 31: Figure 5 Call Control Message Exchange Example
After the switch receives User 2 terminal’s ALERTing message, it sends a corre- sponding ALERTing message to User 1 with Signal=Ring Tone. When User 2 picks up the handset, the terminal sends the switch a CONNect message, indicating the selected channel. The switch returns a CONNect ACKnowledge, and completes a B Channel circuit between the switch and User 2. -
