Introduction

The Netopia 4753 provides small and medium sized businesses with a complete Centrex PBX system. It supports voice call switching between the SDSL link and eight local extensions. Call management features can include distinctive ringing, intelligent call forwarding, Direct Inward Dial (DID), Caller ID, and hunt groups. Important key system features such as call hold, call transfer, and call waiting are all supported.

Note: Since the Netopia 4753 is a Centrex-based IAD, specific voice features available to you via the Netopia 4753 will depend on the services for which you contract with your service provider.

The Netopia 4753 supports up to eight telephone extensions and up to eight derived voice lines. Like the rest of the 4700-series line, the Netopia 4753 includes the Netopia data routing engine for any number of attached computers or other network devices connected to a single 10/100 Ethernet port.

Key features include:

■Fax/Modem: Configurable Voice port for incoming fax or modem calls. This is another term for echo cancellation support.

■Voice Gateway Interoperability: CopperCom, JetStream, Tollbridge TDSoft, Zhone. General Bandwidth support to follow in an upcoming firmware release.

Centrex is a simpler variation on the PBX. It is a PBX with all switching occurring at a local telephone office instead of at the company's premises. Typically, the telephone company owns and manages all the communications equipment necessary to implement the PBX and then sells various services to the company.

Explanation of terms

Some telephony terms mean different things in Centrex mode and PBX/local switching mode: Toll Restriction, Speed Dial, and Distinctive Ringing. The Netopia 4753 operates in Centrex mode.

■Toll Restriction Operation - Centrex Mode: When you pick up the phone, you receive a dial tone from the central office. When 9 is pressed, the Netopia 4753 detects 9 and returns a busy tone (locally generated). Incoming calls are allowed. This allows local extension calling through the central office, but not long
