Compliances

MiVoice Digital Phones meet the requirements of:
ANSI/TIA/EIA-810-A "Transmission Requirements for Narrowband Voice over IP and Voice over PCM
•
Digital Wireline Telephones"
In addition, the 3300 ICP meets all local specifications for each Mitel business region.

Line and Trunk Support Characteristics (North America)

The North American variant of the system supports the following line and trunk parameters:
Station Loop - The industry standard station loop range, including the station apparatus, can be up to
•
a maximum of 600 ohms (ONS Line).
DNI Device Ranges - Any device which interfaces to a DNI line card has a loop length of 2 kilometers
•
(6600 ft.) with 24 (0.6mm) or 26 (0.45mm) AWG twisted pair cable with no bridge taps, and one kilo-
meter with a maximum of one bridge tap of any length. A maximum of 50 m (162.5 ft.) of 22 AWG
(0.7mm) quad cable may also be used.
CO Trunk Loop - The system operates with CO Trunks up to a maximum of 1600 ohms loop resistance.
•
CO Trunk Seizure - The nominal seizure resistance
•
for AMB/AOB V1 trunks: 320 ohms at 20 mA
–
for AMB/AOB v2/v3, ASU II and AX trunks: 370 ohms at 20 mA
–
CO Trunk Resistance - The on-hook DC input resistance of the LS trunks is not less than 5M ohms.

Loss Plan Matrices

Each country has stipulated requirements concerning acceptable transmission performance for tele-
phone systems. The loss plan matrices provide the correct electrical losses in decibels (dB) for each
connection to meet the specified requirement.
Loss plans have a direct effect on the acoustic levels provided at the set. Part of meeting the requirements
is to identify the reference set requirements for all standard and proprietary sets to be used in each
country. It is generally desirable to achieve the same relative loudness levels for all standard and propri-
etary telephones for a specified loss plan, taking into account loop lengths, transmission format (analog
or digital), different transducers in use, line/trunk impedances, and terminating impedances. In the loss
plans, positive values are losses and negative values are gains. The losses are shown in one direction
only (outgoing, from the specified port type); the reverse path loss can be found by using a second
look-up.

NOTE
MiVoice Digital Phones and MiVoice IP Phones meet the following ITU-T recommended loudness
1.
rating: - Send Loudness Rating (SLR) 8 dB - Receive Loudness Rating (RLR) 2 dB.
