The Link Peripheral Processor (LPP) is a high capacity vehicle for services
such as frame relay, packet switching, CCS7 call control and ethernet
interface. The LPP is required to support the Ethernet Interface Unit (EIU).
Users of smaller Meridian SL-100 systems that do not require such high
capacity as the LPP, require a more economical method of accessing
EIU/LPP services. The SSLPP is an alternative to a full Link Peripheral
Processor where:

Frame Supervisory Panel
The FSP distributes and controls power and alarms in the cabinet.
Cooling unit
The high-capacity cooling unit consists of four, high-speed DC-powered fan
blowers. Two of these four fans are operated with a separate power feed
for reliability.
Power requirement
The LPP cabinet is powered by an external -48 V DC source provided by an
CPDC. LPPs require the CPDC as a power source and cannot be powered
by an MCAM unit. The CPDC cabinet is described in

Cabinetized Multi-Vendor Interface

The CMVI provides the multi-vendor interface between the Meridian SL-100
system and the S/DMS AccessNode and other Remote Digital Terminals
(RDTs). The Subscriber Carrier Module-100 Access, second version
(SMA2), which resides in the CMVI cabinet, allows the Meridian SL-100
system to connect to the Fiber Central Office Terminal (FCOT) in the S/DMS
AccessNode or any T1-based access platform from any supplier that
conforms to the Bellcore standard TR-TSY-000303 (TR-303).

The number of Link Interface Unit (LUI7) Application Specific Units
(ASUs) desired does not make the full LPP a cost-effective option.
Offices lacking floor space near the core processor makes it impossible
to install an LPP cabinet.
Note: For detailed information about the LPP, refer to the Peripheral
Modules.
Note: The SMA2 is also known as the Enhanced SMA (ESMA).
