A |
|
auto registration | Process by which Cisco CallManager automatically detects and adds new IP telephony devices to its database, assigning the next available directory number designated for the device type. |
C |
|
call forwarding | Feature of telephony systems that sends incoming calls to a particular directory number to another number. |
call waiting | Feature of telephony systems that notifies caller when another call is coming in during an active call. |
CDP (Cisco Discovery Protocol) | Device-discovery protocol that runs on all Cisco-manufactured equipment. Using CDP, a device can advertise its existence to other devices and receive information about other devices in the network. |
Cisco CallManager | Software-based call-processing component of the Cisco IP telephony solution, which extends enterprise telephony features and functions to packet telephony network devices such as IP phones, media processing devices, voice-over-IP (VoIP) gateways, and multimedia applications. |
Cisco IP Phone | Phone designed to work with Cisco IP telephony systems. The DPA 7630/7610 appears as multiple Cisco IP Phones to the Cisco CallManager system. |
community strings | Passwords used by SNMP to remotely manage network devices. |
D |
|
DHCP (Dynamic Host Control Protocol) | Protocol that dynamically allocates and assigns an IP address to network devices. |
directory number | Unique phone number assigned to devices in the Cisco CallManager database. |
DNS server | Server that maintains a database for resolving host names and IP addresses, allowing network devices to query the DNS to specify remote computers by host names rather than IP addresses. |
DPA (digital PBX adapter) | Gateway device used to integrate Cisco CallManager with other Octel and Lucent systems in an IP telephony network. |
H |
|
host name | Name that identifies network devices on the TCP/IP network, enabling you to access the device using this name rather than the IP address. |
hunt group | Series of directory numbers organized to share the load in such a way that if the first line is busy, the next line is "hunted" until an available number is found. |
I |
|
integration mode | Method of using the DPA 7630/7610 to integrate Cisco CallManager, Octel, and Lucent systems. Includes simple, hybrid, and multiple integration modes. |
IP (Internet Protocol) | Messaging protocol that addresses and sends packets across the network. To communicate using IP, network devices must have an IP address, subnet, and gateway assigned to them. |
IP Address | 32-bit address assigned to hosts using TCP/IP. An IP address belongs to one of five classes (A, B, C, D, or E) and is written as 4 octets separated by periods (dotted decimal format). Each address consists of a network number, an optional subnetwork number, and a host number. The network and subnetwork numbers together are used for routing, while the host number is used to address an individual host within the network or subnetwork. A subnet mask is used to extract network and subnetwork information from the IP address. |
M |
|
MAC address (Media Access Control Address) | Address identified at the Media Access Control layer in the network. All network devices have unique MAC addresses. |
MWI (message waiting indicator) | Method of indicating that a voice mail message was left for a particular directory number. Cisco IP Phones indicate this by lighting an LED on the handset. The DPA 7630/7610 works with Cisco CallManager, Octel, Lucent, and Nortel systems to ensure that these MWIs are set properly. |
N |
|
NTP (network time protocol) | Protocol that ensures that computer systems are set to the same time, relative to Greenwich Mean Time. The DPA 7630/7610 supports NTP to access a designated NTP server in the network to ensure the time in the logs is properly set. |
P |
|
PBX (private branch exchange) | Call processing device used in traditional (analog or digital) telephony networks. The DPA 7630/7610 can interact with Lucent PBX systems to enable messages between callers on them and Cisco CallManager systems to be handled properly. |
pilot directory number | Primary directory number used by users to access voice mail. Different hunt groups have different pilot directory numbers. |
R |
|
RTP (Real Time Transport Protocol) | A standard for transporting real-time data, such as interactive voice and video over data networks. |
S |
|
Simple Network Management Protocol (SNMP) | Method by which network management applications can query a device using a supported Management Information Base (MIB). |
subnet mask | Used to partition the IP address into a network and a host identifier. The subnet mask is used to mask a portion of the IP address so that TCP/IP can distinguish the network ID from the host ID. |
T |
|
TFTP (Trivial File Transfer Protocol) | Protocol that allows transfer of files over the network. TFTP requires a TFTP server in your network, which can automatically be identified from the DHCP server. |
V |
|
voice mail system | Devices used to record, store, and retrieve voice messages. The DPA 7630/7610 integrates with Cisco CallManager and the Octel voice mail system. |
Voice over IP Protocol (VoIP) | Protocol that enables transfer of voice communications over a data network using the Internet Protocol. |
