Outline

JOYIT Programmable Signaling Collecting Unit (JOY-PCU) strides the signaling links of signaling network through high-resistance access for real-time collection of signaling messages at signaling links. After preliminary analysis and processing, the messages unconcerned with the service are filtered away and generated to the messages required. Followed the messages are transferred to Background Application Platform (APP) through TCP/IP, thus APP performs the following services.

With the advanced and up-to-date technology, the products of Programmable Signaling Collecting Unit (PCU) support E1/T1 interfaces and multiple links. In view of the system design, it adopts the modularization structure to cater for memory expansion and update for the smooth and uninterrupted services of the subscribers.

Characteristics

• Support data acquisition for signaling protocols of SS7 and HDLC;
• Support multiple interfaces of E1/T1;
• Collect signaling links with 64K, N*64K and 2M ;
• Collect any time slot among 1~31 of E1 and any time slot among 1~24 of T1;
• The stand-alone collecting capacity may reach up to 16 * 2M or 496 * 64K;
• Time Synchronization System ensures the sequence of message packages;
• Provided with double CPU processing frame and distributed processing mode;
• Modularization design and infinite superposition ensure high volume application supports;
• Network building methods are flexible and variable so as to support a host of service applications.
