Serial Ports
Note This section applies only to Cisco Unified Videoconferencing 3545 Serial Gateway.
In the Physical Interface section of the Serial Port tabs, you can control the properties of the cable connected to the specified serial port. When a cable is connected to a serial port, the gateway identifies the type of the cable and displays the information in the Interface and Physical standard fields of the Physical Interface section. In such cases, you cannot modify these fields. If the gateway does not detect a connected cable, you can modify the Interface and Physical standard fields. For changes to settings in these fields to take effect, the system should be rebooted.
Gateway line cables are attached to the gateway via a DB-60 connector that provides the serial line connection for the gateway serial ports. The cables are Y-type with split leads at the remote end. On one side is either a V.35, RS-449, EIA-530, or EIA-530A connector. On the other side is an RS-366 connector.
Gateway terminal adapter cables have either a DTE or a DCE interface.
The gateway can identify which type of cable has been connected to its DB-60 serial ports. Cable configuration settings are automatically displayed in the Physical Interface section of the Port tabs. The automatically configured settings are shown in Table 7-1.
Procedure
Step 1 In the gateway interface, on the sidebar, click Gateway (if not already selected).
Step 2 Click the applicable Port tab.

About NSF Settings
The NSF Information Element (IE) feature enables system administrators to coordinate network and service requirements with service providers. Service providers supply the information that you enter in the NSF Configuration dialog box. System administrators can either select any of the pre-configured NSF settings, or choose to configure their own NSF Information Element using service provider information.
You can specify the following information in the NSF:
•The service providers with which you want their network to work.
•The specific network plan and equipment with which you want your network to work (for example, switches and bandwidth).
•The specific services available to their network (for example, 1-800 phone numbers).
Instructions are contained in the NSF IE fields of outgoing Q.931 setup messages in the format shown in Table 7-3.
Figure 7-1 Network Specific Facility Information Element Format
NSF Information Elements contain a number of configurable Octet fields. The values entered in these fields represent instructions contained in outgoing Q.931 Setup messages. Table 7-3 represents the format of such instructions. Table 7-4 describes the function of each of the Octet fields.

Deleting ISDN Information Elements
In the Advanced ISDN section of the PRI Port tabs, you can delete an ISDN information element.
Procedure
Step 1 In the gateway interface, on the sidebar, click Gateway (if not already selected).
Step 2 Click the applicable PRI Port tab.
Step 3 Click Advanced ISDN.
Step 4 Select an ISDN information element and click Delete.
Configuring Port Call Policies
In the Call Policies section of the PRI Port or Serial Port tabs, you can configure the incoming call routing methods available in the gateway for each specified port. You can define each port with different settings.
Procedure
Step 1 In the gateway interface, on the sidebar, click Gateway (if not already selected).
Step 2 Click the applicable PRI Port or Serial Port tab.
Step 3 Click Call Policies.
Step 4 Select the Same as Port check box to duplicate call policies settings from another gateway port that you choose from the field. When selected, you cannot modify any settings in this section. This option is unavailable in gateways that support only one PRI port.
Step 5 In the Enable inbound routing methods section, you can select incoming call routing methods in the following order of priority:
•DID—When selected, enables Direct Inward Dialing to an endpoint.
•TCS4—When selected, enables TCS4 dialing. This setting does not apply to voice calls.
•IVR—When selected, enables the Interactive Voice Response operator.
•Default extension—When selected, enables the use of the defined default extension number.
Step 6 (PRI gateways only) Select Overlap Receiving to enable overlap receiving functionality.
In this functionality, the gateway can receive consecutive digits until the dialing is complete, instead of receiving the entire phone number as a block of digits. The gateway recognizes that an overlap receiving dialing is completed when it receives a fixed, predefined, incoming number of digits.
If the gateway receives a complete indication notification from the switch (PSTN) or a timeout before all the digits have been dialed, the call might connect to a different address or rejected. If you select this setting, perform step 7, otherwise skip to step 8.
Step 7 (PRI gateways only) In the Incoming number of digits field, enter the number of digits you want the gateway to expect during overlap receiving.
The gateway waits until this number of specified digits is received and then processes the whole number. You can enter any value up to 32.
Step 8 (PRI gateways only) In the Outgoing Calling Party Number field, enter a number that the gateway automatically provides if the calling IP network endpoint does not provide a calling party number.
Valid digits are 0 through 9 You can enter up to 11 digits.
Step 9 (Serial gateways only) In the Display name for incoming calls field, enter an alias for this serial port. The gateway sends this alias to the IP endpoint in serial-to-IP calls.
Configuring Port Supported Services
In the Supported Services section of the PRI Port or Serial Port tabs, you can enable or disable specific gateway services on each port. The Supported Services section displays the following information:
•Prefix—Displays the prefix for this service.
•Description—Displays a brief description of the service.
•Call Type—Displays the call media type: Voice or Video.
•Bit Rate—Displays the maximum total bit rate allowed for this service.
•Support—Displays the status of the service: enabled or disabled.
Procedure
Step 1 In the gateway interface, on the sidebar, click Gateway (if not already selected).
Step 2 Click the applicable PRI Port or Serial Port tab.
Step 3 Click Supported Services.
Step 4 Select Same as Port if you want to duplicate settings from another gateway port that you choose from the field.
When selected, you cannot modify any settings in this section. This option is unavailable in gateways that support only one PRI port.
Step 5 To enable or disable a service for this port, select it and click Enable or Disable.
