GR-303 Express

The GR-303 Express (GEM-X)is an integrated software product suite that builds upon EDI Enterprises' popular GEM product. The GR-303 Express revolutionizes GR-303 implementation by providing a single-vendor, complete stack from LAPD all the way up to the EOC and TMC protocols. RDT and IDT vendors who already support GR-303 hardware and driver requirements will be amazed at how quickly they will be making calls.

The GR-303 Express includes the following features:

Supports IDT and RDT interfaces.
Proven implementation for LAPD/Q.921:

Optional real-time calculation of data link layer statistics.
Includes customizations specified in GR-303-CORE.

Proven implementation of Q.931 as per GR-303-CORE.

Traditional Q.931 primitive interface and simplified API interfaces provided.

Proven EOC implementation:

The GEM-X implementation educates developers on what portions of the EOC are important.
Default MIB provided with compact object data representation.
Integrated EOC and TMC path protection switching state machine.
Integrated analog line state machine.
Integrated RDT alarm generation system that can be configured based on the switch type.

EOC and TMC software can be integrated to customer-provided LAPD/Q.931.
Interoperability tested against popular switching and loop carrier systems.
Interoperability tested at Telcordia.
Written and delivered in ANSI C.
Compact code and data usage is ideal for embedded, real-time environments.
GEM-X modules adhere to a common, platform-independent architecture that utilizes the tasking structure available from the customer RTOS.
Single-board implementations can often be integrated to customer HDLC, RTOS, and IPC by an EDI engineer within one week!
Optional integration packages available from EDI provide different levels of integration support dependant on customer need.
GEM-X is a loosely coupled suite of products allowing component products to be distributed to different hardware components in a system.
Integrated hardware redundancy support.
Single-vendor source ensures efficient problem resolution. All source code modules have been developed in-house.
GR-303 and GEM-X product training included with purchase price.
Example application code provides developers a hands-on jump-start in using the GEM-X software.
GEM-X can coexist in the same running software with other EDI protocol products (e.g. V5-X and ISD-X).
Code tracing and event/state display debug facilities included. Debug facilities can be compiled out to save code space. When compiled in, they can be selectively enabled at runtime.
Extensions available for Nortel P-Phone.
