➻10-03-13 : PCB Setup - Loss-of-Signal Detection Limit

Setup and confirm the Basic Configuration data for each PCB. Select the loss-of-signal detection limit. In short-haul mode: 0=0.91V, 1=0.74V, 2=0.59V, 3=0.42V, 4=0.32V, 5=0.21V, 6=0.16V. 7=0.10V. In long-haul mode: 0=1.70V, 1=0.84V, 2=0.84V, 3=0.45V, 4=0.45V, 5=0.20V, 6=0.10V, 7=not defined

➻10-03-14 : PCB Setup - Service Protocol for S-Point

Setup and confirm the Basic Configuration data for each PCB. Select the service protocol to be used (0=keypad facility, 1=specified protocol for Aspire).

➻11-01-01 : System Numbering

Set up a Service Code for Alternate Trunk Route Access. You may want to use an alternate access code for your outgoing PRI trunks. Also see programs 11-09-02 and 21-15-01.

Default Setting: No Alternate Trunk Route Access code programmed.

➻11-09-02 : Trunk Access Code - Alternate Trunk Route Access Code

Assign the Service Code set up in 11-01-01 for Alternate Trunk Route Access. You may want to use an alternate access code for your outgoing PRI trunks. Also see programs 11-01-01 and 21-15-01.

Default Setting: No Alternate Trunk Route Access code programmed.

➻14-01-02 : Basic Trunk Data Setup - Transmit CODEC Gain Type If required, adjust the transmit CODEC gains for each trunk.

Default Setting: 1 (0 dB transmit gain)

➻14-01-03 : Basic Trunk Data Setup - Receive CODEC Gain Type If required, adjust the transmit CODEC gains for each trunk.

Default Setting: 1 (0 dB receive gain)

➻14-01-07 : Basic Trunk Port Setup - Outgoing Calls

Allow this option (1) for each PRI trunk you want to use for outgoing calls. Prevent this option (0) if the trunk will not be used for outgoing calls.

Default Setting: Outgoing calls allowed (1).

➻14-01-10 : Basic Trunk Data Setup - DTMF Tones for Outgoing Calls

For each trunk, enable (1) or disable (0) DTMF tones for outgoing trunk calls. Default Setting: DTMF tone disabled for outgoing calls (0).

➻14-05-01 : Trunk Groups

Assign the PRI trunks to trunk groups. This determines the channels available for PRI lines. Default Setting: All trunks assigned to Trunk Group 1.

➻14-07-01 : Trunk Access Map Setup

Set up Trunk Access Maps (200) for PRI trunks. You must also assign extensions to Trunk Access Maps in Program 15-06-01.

Default Setting: All trunks in Access Map 1 have full access (7). All trunks in the other Access

Maps have no access (0).

➻15-01-04 : Basic Extension Data Setup - ISDN Caller ID

If both Program 15-01-04 and 10-03-05 are enabled (1), the system includes Caller ID in the Setup message as “Presentation Allowed”. If these options are disabled (0), it will be “Presentation Restricted”.

ISDN-PRI specifications

NEC ISDN-PRI (Integrated Services Digital Network - Primary Rate Interface) is a telecommunication standard that provides high-capacity voice and data transmission over digital networks. Offering exceptional reliability, ISDN-PRI has become a crucial component for businesses seeking robust communication solutions. One of the standout features of NEC ISDN-PRI is its ability to support 23 voice channels, each capable of delivering clear and high-quality audio simultaneously. In addition to voice channels, ISDN-PRI can also handle one data channel, facilitating data transmission at speeds of up to 2.048 Mbps.

A significant characteristic of ISDN-PRI is its digital nature, allowing for efficient use of bandwidth and minimizing issues common in analog systems, such as signal degradation and noise. This technology leverages time-division multiplexing (TDM), which enables multiple voice signals to occupy a single transmission medium without interference. Each channel is allocated a specific time slot, ensuring a seamless communication experience.

NEC ISDN-PRI is also known for its features such as call setup and teardown capabilities. Utilizing the D channel, ISDN-PRI can establish and terminate calls quickly, enhancing overall call management and enabling businesses to handle high volumes of concurrent calls efficiently. Moreover, businesses can benefit from supplementary services, including caller ID, call forwarding, and call waiting, which enhance operational efficiency and customer service.

Security is another critical aspect of NEC ISDN-PRI. The technology includes features like encryption and secure access protocols, ensuring that sensitive data remains protected during transmission. These security measures are vital for businesses dealing with confidential information and seeking to comply with industry regulations.

Furthermore, ISDN-PRI is highly compatible with various telecommunication infrastructures, making it a versatile choice for organizations looking to upgrade or integrate their existing systems. The ability to connect to PBX systems and support multiple protocols adds to its appeal, providing businesses with scalability and flexibility as their communication needs evolve.

In summary, NEC ISDN-PRI stands out as a reliable and efficient communication solution. With its support for multiple voice channels, high data transmission rates, robust security features, and compatibility with various systems, ISDN-PRI is well-suited for modern business environments seeking to enhance their communication capabilities and improve overall operational efficiency.
