Configuring ISDN network-side emulation
You can configure PRI lines to use either

ISDN is a nonsymmetrical protocol used by telephone carriers to provide digital services to end users. There are no ISDN links between telephone carrier Central Offices (COs). ISDN links exist only between the CO and the customer. Therefore, an ISDN link can be viewed as having two sides— the network side, or network terminating (NT) equipment, and the user side, or terminal equipment (TE). The user side can connect only to the network side, and vice versa. Both the network side and the user side perform the same functions, but the format of the messages is different. For example, the network side must always set a bit and the user side must always clear it. These differences allow either side to determine whether the other end is the right one.
ISDN emulation enables you to build, send, receive, and process ISDN data. ISDN monitoring, on the other hand, allows you only to decode the ISDN data.
Configuring overlap receiving on PRI lines
Overlap receiving affects the procedure of establishing an incoming call received on a T1 or E1 PRI line in the TAOS unit. With overlap receiving, the TAOS unit can gather the complete called number from the network switch via a series of Information messages, enabling the use of features such as
The Q.931 specification states that either
Following are the relevant parameters, which are shown with sample settings for T1 and E1 lines:
