Network loop assigning
When assigning the loop number in systems equipped with two Network
UEMs, the load should be distributed evenly across both UEMs. Loops
should be assigned in the order shown in Table 2- 1. Record the loops used
.
in Worksheet L provided at the end of this document.
The total number of Peripheral Equipment
UEMs
should be distributed over
the total number of voice and data loops. Normally, one PE UEM is
assigned to a superloop. However, one PE UEM
cart
be assigned from one
half-superloop to as many as four superloops, depending on the
concentration of Terminal Numbers to Timeslot ratio. See Table 2-l for
details on loop number assignments.
Total number of loops = 4 x No. of Superloop Network Cards + 2 x No. of
3nhanced Network Cards

Note: The assignments shown may vary
depending on system configuration and size.
Conference (CONF) and Tone and Digit Switch
(TDS) may be assigned any even loop number.
Do not assign the odd loop number associated
with CONF or TDS loop.
