Application Examples
Figure 1 and Figure 2 show a PM8611 SBI336 Bus Serializer-lite (SBSLITE) connected to a
TelecomBus to implement a T1 or E1 Add/Drop function. When connected to the TelecomBus,
the SBSLITE with a PM8620 or PM8621 Narrowband Switching Element (NSE-8G™ or NSE-
20G™) implements a T1/E1 Memory:Space:Memory switch. The SBSLITE requires all path
pointer justifications to be translated into tributary pointer movements so that J1 is fixed to the
location following C1 or H3. In both examples J1 alignment is performed with the TUPP-622.
Switching within the SBSLITE and NSE is utilizing the Transparent Virtual Tributary, TVT,
mapping across the serial SBI336S LVDS links.
