3System Functions
3.1. Call Processing Functions
Call Processing Functions: Delivers voice via packetized network to call destination.
Basic Functions include:
- Inter-extension connection
- Monitoring/Error Management
3.2. Analog FXS Control Functions
Analog FXS Control Functions are used for SLT connection. It packetizes analog
voice and transmits through digital network to call destination. (call routing function).
3.3. Emergency Call Switchover Function
Emergency Call Switchover Function is a unique function compared to other devices.
The device automatically switches over to PSTN backup line when:
- Power failure
- Device Malfunction
3.4. DTMF / Call Progress Tone Detection & Generation Function
DTMF/Call Progress Tone Detection and Tone Generation Function detect and
generate inband-tone transmitted over an analog line.
3.5. Voice Compression & Decompression Function
Voice Compression is the packetizing of PCM-coded voice data. Decompression is
conversion of packetized voice data back into PCM-code. Supports G,729.a, and
G.723.1 Voice Coding mode.
The actual voice compression/decompression is processed inside of Digital Signal
Processor and the functional unit controls DSP H/W.

3.6. VoIP Function
H.323 protocol provides voice service through IP network by way of sending digital
voice-data packetized and encoded via IP network to process its calls. This function is
complied with ITU-T : H.323 Recommendation.
SIP is a text-based protocol that is based on HTTP and MIME, which makes it suitable
and very flexible for integrated voice-data applications. SIP is designed for real-time
transmission, uses fewer resources and is considerably less complex than H.323. Its
addressing scheme uses URLs and is human readable.
3.7. TCP/UDP/IP Protocol Processing Function
TCP/UDP/IP Protocol Processing Function processes various Protocols like TCP
complying with RFC793, UDP with RFC768 and IP Protocol with RFC791.
3.8. Ethernet Control Function
Ethernet Control Function is to process MAC, Ethernet protocol or IEEE 802.3
Protocol and perform ARP for TCP/IP communications with CSMA/CD data network.
3.9. FAX Relay Function
FAX Relay Function is to send Facsimile Data instead of voice data through
packetized network so that FAX data may be packetized and terminated via internet.
3.10. Console Command I/O Function
Console Command I/O Function is to operate and manage the equipment through the
console at the site in which the equipment is installed. It decodes a command typed in
the console to perform the operation.
3.11. Telnet Remote Control Function
Telnet Remote Control Function is for an operator to access the equipment using
RFC854 Telnet Protocol in a remote system for operation and management. The
operator may see and maintain the system via access through Telnet from a remote
1 - 10

location.
3.12. Diagnostic Function
Diagnostic Function is use when there is a need for customers or operators to test the
device. Test results give limited information to customer/operator but serves as a
vital tool to provide optimal customer service.
3.13. DHCP Function
DHCP Function is needed to dynamically assigned IP address, net-mask, and default
gateway for the DV-201DM. DV-201DM has DHCP client in it and performs the
function of changing IP addresses, net mask and default gateway.
3.14. WEB-based Management Function
Web-based management function is needed to set DV-201DM configuration
parameters remotely through web browser. Operator is permitted to access DV-
201DM to change configuration parameters through web browser or through HTTP
protocol.
3.15. Operation Authentication Function
Operation authentication function is needed to authenticate an operator by prompting
the user ID and password when the operator access DV-201DM
3.16. Configuration function with connected telephone
This function enable you to set DV-201DM initially using connected telephone. So you
don’t have to access to the device for setting with telnet or http connection. Just
connect telephone to the device.
3.17. Remote Upgrade Function
For remote maintenance or when S/W upgrade is necessary in the system using ftp
service.

3.18. Configuration Data Server Function
With CDS Server, configuration data is downloaded to the system automatically and
automatically installed
3.19. TFTP/ FTP Processing Function
TFTP processing function is for remote maintenance and performs functions defined
in RFC1350.
FTP processing function is for remote maintenance and performs the functions
defined in RFC1986.
