System expansion worksheet

Complete one worksheet for each MIG RLC.
1 How many remote users will be supported?
Notes:
Up to 16 users can be connected to the NTDR68AA Line Card. Up to 32
users can be connected to the NTDR70AA or NTDR71AA Line Cards.
If ATAs or MCAs will be used to transmit data, up to four ATAs or MCAs
can be supported on the NTDR68AA Line Card. Up to seven ATAs or
MCAs can be supported on the NTDR70AA or NTDR71AA Line Cards.
Each ATA requires the resources of one DSP channel for data
transmission.
2 Do you want to implement call blocking? (Users will receive a
fast busy signal when resources are not available.)
3 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 1 by your call blocking factor. For example, to calculate the number
of simultaneous calls that can be supported at a 3 to 2 blocking ratio, multiply
line 1 by 2/3 (0.666). If the result contains a fraction, round up to a whole
number.
Line 1: _________ x ___________ = _______________
If line 7 is No, the number of simultaneous calls is the same as the number of
user stations installed. (Record your response to line 1 here.)
Number of DSP application modules needed
Notes:
If the MIG RLC supports only one Remote Office 9150 unit, the number of DSP application
modules installed on the MIG RLC must be the same as the number of modules installed on the
Remote Office 9150 unit.
If the MIG RLC is supporting more than one site, the number of DSP applications modules you
need must support the voice processing capability for all sites combined.
4 Divide line 8 by 8, then round up the result to a whole number.
Line 8: _____________ / 8 = _______________
