Remote Office 9150

System expansion worksheet

Complete one worksheet for each Remote Office 9150 unit.
Number of stations:
1 How many digital telephones will be installed at the Remote Office 9150 site?
Note: A maximum of 32 digital telephones can be connected to the Remote
Office 9150 unit.
2 How many Analog Telephone Adapters (ATAs) will be installed?
3 How many Meridian Communication Adapters (MCAs) will be installed?
4 Add lines 1 and 2 together.
Notes:
n
A maximum of four MCAs and ATAs can be installed when connecting the
Remote Office 9150 unit to a 1-slot RLC. A maximum of seven MCAs and
ATAs can be installed when connecting to a 2-slot RLC.
n
The total number of ATAs and digital telephones cannot exceed 32.
5 Will a fax machine be used for faxes through the host PBX?
6 If line 5 is Yes, add 1 to line 4.
Call blocking:
7 Do you want to implement call blocking? (Users will receive a
fast busy signal when resources are not available.)
8 If line 7 is Yes, calculate the number of calls that can be active at one time.
Note: A conservative estimate of one call in three being blocked when no
resources are available is recommended.
Multiply line 4 by your call blocking factor. For example, to calculate the number
of simultaneous calls that can be supported at a 3:2 blocking ratio, multiply line
6 by 2/3 (0.666). If the result contains a fraction, round up to a whole number.
Line 6: _________ x ___________ = _______________
If line 7 is No, the number of simultaneous calls is the same as the number of
stations installed. (Record your response to line 6 here.)
