Installation
Multiple connection types can be used to implement theDiscoveryVoIP card in the business
environment. The speed of a network connection is measured in bandwidth or kilobytes per
second (K or kbs). Business connections generally have a speed of 256K or greater. In
comparison, a home user dialing into the Internet with a modem can reach a maximum
speed of 56K.
The two main types of connections are managed and unmanaged. A managed...

Technical Data
Lower bandwidths, lower connection reliability, and high network latency will decrease
DiscoveryVoIP performance. Bandwidths lower than 256K and network latency higher than
120 ms may cause unacceptable performance. Intermittent fluctuating connections (i.e.,
some wireless broadband connections) will cause unacceptable performance problems.
Have your network administrator check your network performance and bandwidth to
determine...

IP Phones
IP phones using the H.323 Revision 2 protocol will work with theDiscoveryVoIP card. The IP
phone, however, will not be integrated into the system. Instead, the IP phone resembles a
single-line telephone that uses the Internet or other IP network instead of the PSTN. IP
phones allow dialing using the IP address of the...

Programming
The following Table shows the Network programming requirements.
Identifying the VoIP Card (FLASH 24)
TheDiscoveryVoIP card can be placed in slots 1-7 of Cabinet 0 and in slots 0-8 of Cabinet 1
and Cabinet 2. Once the slot is identified, it takes the required time slots and deducts them
from the available ones. It activates all 8 circuits. If more then one card is identified, each card
is identified in the same manner and it requires...

Entering Network Programming Requirements (FLASH 46)
Flash Code 46 is for the specific network programming requirements for theDiscoveryVoIP
card. IP address, subnet and router address information must be entered for the VoIP card to
work. Each card installed in the system requires a separate IP address and subnet mask. The
router address and domain name may be shared. See your network administrator for
networking information.

Networking Tables (FLASH 16)
Networking Tables identify the system number (01-16), the CO or line Group (00-23), the
range of station numbers (from xxxx to xxxx), and the IP address for each system. The system
number is a database identifier. The CO or line group identifies the line group the system
should access when the associated extension number is dialed. The extension range defines
the extensions that can be reached at the associated...

»Feature access codes must not conflict with station numbering.
»CO line numbers are fixed and cannot be changed other than the current FLASH 42
reassignment.
»The VMID digits need to be programmed separately.
»The SMDR will output up to 4-digit numbers in the station field. If less than 4 digits are
selected in the numbering plan, leading spaces will be added in place of numbers. Call...

Operation
TheDiscoveryVoIP card operates like all other Central Office cards. There are up to 8 lines per
card, and each line functions as any other CO line functions. It allows bi-directional
communication and monitors for disconnect while using minimal bandwidth. It also allows
four-digit dialing and other features.
