Further, as protocols evolve, the NPs can be repro-
grammed in software to address new requirements.
C-Port NPs support higher-level programming in
C-language with Applications Programming Interfaces
(APIs), enabling fast development of advanced features
by which you may differentiate your products.
With the extensive architectural flexibility of the C-Port
family, a single line card can be designed to interface to
numerous types of PHY modules supporting a vast range
of application requirements. This greatly simplifies sys-
tem architecture because nearly every interface that a
Radio Access Network (RAN) needs to support can be
based on a common hardware platform.
An example of a line card using a C-3e NP in a BSC is
shown in the diagram. This example shows T1/E1 lines
from a BTS connecting to the C-3e NP through Motorola
TDM adapter technology. The C-3e NP line card then
connects to a mobile switching center through OC-3c/
STM-1. The only components that change for different
interface configurations would be the line interface logic
itself. For example, the C-3e NP could also support
uplinks of Ethernet.
Eight of the C-3e NP
’
s Channel Processors (CPs) are
available for implementing more advanced networking
functionality. In the example, they are performing AAL-2/
AAL-5 Segmentation and Reassembly (SARing), as well
as IP and ATM traffic management on traffic moving
upstream and downstream through the BSC. For
applications that may require more extensive Quality of
Service (QoS) capabilities, you can add one of Motorola

s
Traffic Management Coprocessors (TMCs), which pro-
vides policing, shaping, and scheduling for up to 128k
individual flows.
