Cisco Cisco 2600 3600 Series 1-Port 30-Channel J1 Voice Fax Network Module 技術マニュアル
Configuration
Refer to
for the configuration of voice features in Cisco IOS Software.
Note: In Cisco IOS Software, use the global configuration command voice-port slot/VIC slot/unit to configure the voice port parameters.
Before you configure the VIC E&M, be sure you understand the different interface types and wiring arrangements that an E&M port can have. E&M
interface types can be type I, II, III, or V. Cisco platforms do not support type IV. Wiring arrangements can be two or four wires. Refer to
interface types can be type I, II, III, or V. Cisco platforms do not support type IV. Wiring arrangements can be two or four wires. Refer to
for more information.
Also, you need to understand the different types of Start Dial Supervision signaling that an E&M port can have. Start Dial Supervision is the line protocol
that defines how the equipment seizes the E&M trunk and passes the address signaling information. The equipment sends dual tone multifrequency
(DTMF) digits in order to pass the address information. On E&M circuits, the three main Start Dial Supervision protocols are:
