Mitel Voice Processing Solutions Installation And Service Manual

							Dual Tl Digital Trunk Connectivity
1--811Model 70 and Model 
1201 supports only one digital trunk for a maximum system
capacity of 24 
KM voice channels. The Model 120s and the Model 640 module
each supports up to 60 PCM voice channels between two digital trunk interface
cards.You assign the slot at the Physical Resource Configuration Menu for the card you are
configuring.
Module NumberThe module number is the Series 6 server module in which the digital trunk interface
card is installed. A four-module Series 6 Model 640 server can support a total
capacity of 240 PCM voice channels over 16 trunks.(In such 
‘a configuration the
line groups would be configured to use only part of the total number of PCM
channels 
- that is fractional Tl - available in each trunk. Refer to “TlConnectivity Features” on page 7.) You assign the slot at the Physical Resource
Configuration Menu for the card you are configuring.
Input/Output AddressThe digital trunk interface card can occupy one of two possible AT bus addresses:
Ox3OOh and Ox2300h where address Ox300h is the default address occupied by card 0
and 
Ox2300h is assigned to card 1. These addresses can also be assigned to a
Smartcard in Model 70 and 
I201 servers. Before selecting the I/O address, check the
addresses occupied by these cards if they are present in the affected Series 6 server
module. If these cards are and either of their addresses are set to the same to which
the digital trunk interface card, an address conflict exists and bus contention will
occur. Ensure that each card is set to a unique address. The address selected in the
Select IO Address Menu must match the address for which the card is physically
jumpered.
Note:The digital trunk interface card has jumper positions for setting
interrupt request levels.
However, the 
VoiceMemo application
polls the hardware to detect status and service the cards and does
not use hardware interrupt requests.
You set the card 
I/O address in the Configuration Menu for Board [DUAL Tll in
AT slot x.
SignalingEach channel in the digital trunk interface can be set for one of these four types of
channel associated signaling according to the requirements of 
CSUs, channel banks,
or other related equipment to which the Series 6 server is connected:

l Loop start
l Ground start
lDirect Inward Dial (DID)
. E&M
You set the trunk signaling in the Select Trunk Type Menu. The menu has options
for both analog and digital trunks. However, when you are configuring a digital
trunk interface card, the configuration manager accepts only the digital trunk
options.
Trunk ConfigurationTrunk configuration includes the trunk number, framing format, and coding format.
Trunk Sequence NumberThe trunk number is the logical number of the trunk, 
beginningwith trunk number
0 on trunk card 1. You set the trunk number at the Configuration menu for 
Tl/ElCarrier at trunk x Menu.
Framing FormatThe Series 
G server supports D4 12channel frames and extended superframe (ESF)
24 channel frames. You select the framing format the trunk uses at the Configure
Frame Format for Board [DUAL 
Tl] in AT slot x Trunk y Menu.
Coding FormatThe Series 6 server supports 
B8ZS, AM1 (alternate mark inversion) and AM1 with
ZCS (zero code suppression) coding formats for 
Tl trunks. You select coding for
the trunk at the Configure Frame Coding for Board [DUAL 
Tl] in AT slot x Trunk
y Menu.
Clock SynchronizationThe system master clock must be synchronized to the 
nenvork (that is, a selected Tl
F&D signal). The digital clock reference can be set to one of the following:
0Network
l
Default
0Internal (reserved for connections to channel banks)
The network clock referenceis the 
I&D signal of a selected Tl trunk. In the case of
Model 70 and Model 1201, the selected trunk is trunk 0. For Model 
12OS, selected
trunk can be 0 or 1. For Model 640, the selected trunk can be 0, 1, 2, or 3 (only one
trunk can be selected). The default reference is trunk 0.
The Series 6 server features automatic switchover to a backup clock source if the
primary fails. However, this feature functions only when both trunks of a Dual 
TIcard are used and the clock is synchronized to the 
RxD signal of one of them..
2-15 
						

							Dual T1 Digital Trunk ConnectivityThen, if the trunk to which the clock reference is derived, the Series 
G server will
automatically switch over to the second trunk on the Dual 
Tl card.
Note:This clock source switchover feature does not work if digital trunk
connectivity is split between two Dual 
Tl cards.
When configuring the system, use the network clock as the system clock reference to
prevent frame slips (Figure 
2-6). However, use the internal clock reference when the
trunks are connected to channel banks.

Digital Trunk Online MaintenanceThe 
VoiceMemo application has an online maintenance utility for monitoring
digital trunk activity and statistics (either individual trunks or all trunks), changing
the clock reference, removing trunks from service, and looping back trunks toward
the facility. Trunk activity includes the operational state of a trunk, 
errored seconds,
frame slips, and so forth. The display presents trunk status and the configuration of
the trunk-a useful feature for quickly validating trunk setup.
The information displayed is dynamic and changes as trunk status changes. For
example, if a trunk is taken out of service, this utility immediately reports it to the
display. Refer to the 
Centignm Series G Diagnostics Manual for further information.

VoiceMemo Release 6.OA and later
Though typically a factory-installed standard feature, the Dual 
Tl digital trunk
connectivity feature can be retrofitted to a Series 6 server in the field. Use this procedure
if you are adding a Dual 
Tl Digital Trunk Interface card to a Series 6 server that you
already have. This procedure presumes that you have already set the card jumpers and
switches and installed it in the Series 6 server.
This procedure gives you the instructions for configuring the feature software to support
a 
Tl digital trunk. Tl trunk configuration is done offline using the Resource Manager.
In this procedure you will set:
lModule number in which the Dual Tl card resides
lI/O port address of the card
lSignaling used on the trunk channels
lTrunk number (0 through 60), framing format (D3/D4 or ESF), and coding (AM1 or AM1
with ZCS)
