Text Part Number: 78-6271-01 Updates to Cisco AS5300 Universal Access Server Module Installation and Software Configuration Guides Product Number: DOC-785891=, DOC-AS5300SWG= This document includes updated information for DSP modules on the Voice-over-IP (VoIP) card for the Cisco AS5300 Universal Access Server Module Installation Guide and the Cisco AS5300 Universal Access Server Software Configuration Guide.
Overview Overview The VoIP capability enables a Cisco access server to carry live voice traffic (for example, telephone calls and faxes) over an IP network. The VoIP card is available as a spare or a factory-installed card within the chassis. Use this document if you are: • • Installing or upgrading 6 session voice modules — Part Number AS53-6VOX (DSPM 542) Installing 12 session voice modules — Part Number AS53-VOXD (DSPM 549) The VoIP card contains multiple digital signal processor (DSP) modules.
Hardware Features The second application (see Figure 2) uses the VoIP card as a PSTN gateway for Internet telephone traffic. This leverages the standardized use of H.323-based Internet telephone client applications.

Safety Recommendations VoIP Card The VoIP card resides in one of the slots in the Cisco AS5300 universal access server. Up to five DSP modules can be installed onto the voice card to perform voice processing for up to 30 B channels for single-density DSPs and 60 B channels for double-density DSPs.
Safety Warnings Waarschuwing Dit waarschuwingssymbool betekent gevaar. U verkeert in een situatie die lichamelijk letsel kan veroorzaken. Voordat u aan enige apparatuur gaat werken, dient u zich bewust te zijn van de bij elektrische schakelingen betrokken risico's en dient u op de hoogte te zijn van standaard maatregelen om ongelukken te voorkomen.
Safety Recommendations Varning! Denna varningssymbol signalerar fara. Du befinner dig i en situation som kan leda till personskada. Innan du utför arbete på någon utrustning måste du vara medveten om farorna med elkretsar och känna till vanligt förfarande för att förebygga skador. Se förklaringar av de varningar som förkommer i denna publikation i dokumentet Regulatory Compliance and Safety Information (Efterrättelse av föreskrifter och säkerhetsinformation), vilket medföljer denna anordning.
Preventing Electrostatic Discharge Damage Caution Before opening the chassis, ensure that you have discharged all static electricity from your body and be sure that the power is OFF. Follow these guidelines when working on equipment powered by electricity: • Locate the emergency power-OFF switch in the room in which you are working. Then, if an electrical accident occurs, you can quickly shut the power OFF.
Required Tools and Equipment • • Wear safety glasses when working under any conditions that might be hazardous to your eyes. Do not perform any action that creates a potential hazard to people or makes the equipment unsafe.
Removing VoIP Cards Warning Before performing any of the following procedures, ensure that power is removed from the DC circuit. To ensure that all power is OFF, locate the circuit breaker on the panel board that services the DC circuit, switch the circuit breaker to the OFF position, and tape the switch handle of the circuit breaker in the OFF position.
Removing and Installing Cards and Modules Caution The EMI protective devices on the VoIP card are designed to make the card fit tightly. When removing the card, they can release suddenly. Exercise caution when removing the VoIP card with the card removal tool.

Installing DSP Modules Removing DSP Modules H11140 Figure 6 Step 3 Orient the VoIP card so that the DSP module socket is facing toward you. Step 4 Gently pry the front edge of the DSP module away from the standoffs and the socket, as indicated by the arrow labeled 1 in Figure 6. Step 5 When the DSP module is free of the socket, gently pry the back edge of the DSP module away from the other set of standoffs, as indicated by the arrow labeled 2 in Figure 6.
Removing and Installing Cards and Modules Note Mate the socket on the DSP module with the socket on the VoIP card. Step 3 Continue with the following section, “Installing VoIP Cards” to install the VoIP card. Installing VoIP Cards To install a VoIP card: Step 1 Remove the VoIP card from the ESD-preventive mat. Step 2 Slide the VoIP card into the slot until it touches the backplane connector. Step 3 Align the captive screws with their holes, and then seat the VoIP card completely.

Cisco IOS Software Requirements Caution Do not overtorque the terminal block contact screws. The recommended torque is 8.2 ± 0.4 inch-lb. (a) Insert the safety ground (green wire) into the terminal block ground connector and tighten the locking screw. Ensure that no bare wire is exposed. (b) Insert the +48 VDC wire into the terminal block positive connector (+) and tighten the locking screw. Ensure that no bare wire is exposed.
CODECs CODECs Some new compression/decompression (CODECs) has been added to the Cisco AS5300 universal access server. The following table lists the available CODECs with their default packet size (in bytes) and their ranges.

Software Features The dtmf-relay command specifies how an H.323 gateway relays DTMF tones between telephony interfaces and an IP network. Options allow the gateway to forward tones as part of the signal or as part of an H.245 control channel. The no form of this command removes all signaling options and transmits the DTMF tones as part of the audio stream.
Preparing to Configure the Software Preparing to Configure the Software Before you can configure your Cisco AS5300 to use VoIP, you must first complete the tasks listed below. If your Cisco AS5300 is already configured to use VoIP, you can skip this section. To configure your Cisco AS5300 to use VoIP: • Establish a working IP network.
Upgrading VoIP Card VCWare For detailed procedures, see the Cisco AS5300 Universal Access Server Software Configuration Guide. You can find the most up-to-date version of this manual online from either CCO or the CD-ROM. • For access to the CCO version of this manual, go to: Services & Support: Technical Documents: Cisco Product Documentation: Access Servers and Access Routers: Access Servers: Cisco AS5300: Cisco AS5300 Universal Access Server Software Configuration Guide.
Identify Voice Cards Identify Voice Cards Use the following steps to identify the voice cards in the system and determine whether the VFC is in VCWare mode or ROM monitor mode. This determines how you download software to the VFC. If there is not VCWare loaded on the VFC, you can use the ROM monitor mode to download the VCWare. Otherwise the VCWare mode is active.
Upgrading VoIP Card VCWare Caution Erasing the VFC files can result in system outage or the corruption of your VFC board. Check to ensure that the correct version of software resides on your TFTP server before continuing. Table 3 Step Replace Firmware in VCWare Mode Command 1 (optional) Purpose Note See the Caution before this table before continuing. 5300# erase vfc slot_number This will erase the contents of VFC Flash. Continue ?[y/n]:yes This will take some time. Please, wait...
Replace Firmware with VCWare in VCWare Mode Verify To check that you have successfully downloaded the software: • Enter the show vfc slot_number directory command to verify that the VCWare is in the Flash memory. Only one filename should appear.
