analog signal at a rate of twice the highest signal frequency, then converts
the amplitude into a series of coded pulses. For telecommunications, the
PCM-sampling frequency standard is 8 kHz.
Compressing-expanding (companding) PCM is a standard technique for
using 8-bit words to efficiently represent the range of voice and data
signals. Two standards for companding, A-Law and µ-Law, are recognized
worldwide. IPE conforms to both standards; the standard required is
selected through software.
IPE is associated with network loops. IPE cards are supported by NT8D04
Superloop Network Card loops. The traffic requirements of all IPE cards
provisioned on a particular network loop must match the traffic capacity
of that loop.
IPE includes:
• controller cards that provide timing and control sequences and
monitoring capabilities
• analog and digital line and trunk cards that provide interfaces to
equipment outside the modules (such as telephones, data terminals,
and trunks)
Table 5 "Intelligent Peripheral Equipment cards" (page 45) lists the IPE
cards and the number of terminations each supports.

Controller cards:

Line cards:
NT1R20 OPS Analog Line card 8
NT5K02 Analog Line card 16
NT5K96 Analog Line card 16
NT8D02 Digital Line card 16 to 32
Note: Terminal number (TN) density per segment is 16 to 128 TNs, with 64 to 512
TNs per IPE module. The maximum TN density assumes all slots are equipped
with NT8D02 Digital Line cards with 16 voice and 16 data TNs provisioned. A
typical mix of line and trunk cards yields a nominal density of 64 TNs per segment,
256 TNs per IPE module.
