Nov 06, 2023

Part.1 -- Company Profile

CAAC Central and Southern Regional Administration, one of the most intensive regional air traffic control authorities in China, is responsible for air traffic control in six provinces, namely Henan, Hubei, Hunan, Guangdong, Guangxi and Hainan, and has 12 air traffic control bureaus and 14 units directly under its jurisdiction.

The communication, navigation and surveillance business is one of the three basic businesses of the air traffic control system, providing ground and air communication, flight navigation and radar surveillance services for air traffic management, which is the foundation of the intelligent air traffic control and the leading industry of scientific and technological innovation of the air traffic control system.

Central South Air Traffic Control Bureau(CSATC)'s original telephone system is Huawei system. Huawei withdrew from the To B voice communication market. And for user, the later maintenance and system expansion is a pain point.

Equiinet helped its partner, Guangzhou Yucheng. Deployed a SINA IP communication system with large number of registrations, which helped users to upgrade current Huawei system and meet the daily office communication and personalized customization needs of the ATC.

Part.2 -- Enterprise Requirements & Solutions

Requirement 1: The first stage of the communication system needs to support 4,500 registrations, and the second stage needs to scale up to 15,000 registrations. Meanwhile, in order to ensure the high stability of communication, the system needs to support high capability.

Equiinet's solution : Provide SINA system for Central South Air Traffic Control Bureau, which can support 4,500~20,000 people to scale up in the second stage, and set up two sets of SINA system, with high availability, which can highly guarantee the stability of the communication .

SINA, best choice for company with more than 1,000 registrations

Requirement 2: At present, all phone lines of CSATC are deployed on Huawei's CC08, and customer hope that the phone lines can be connected to the SINA system without changing current wiring.

Equiinet Solution: Set up two EQ-8E1 gateways to connect with Huawei CC08. Using SIP protocol to connect the E1 gateway with the SINA system, Real story scenario: the SINA system can make incoming and outgoing calls through the phone lines of Huawei CC08.

EQ-8E1

Requirement 3: Customer wants to keep the current analog phones, which are currently partially connected to Huawei UA5000 and partially connected to IAD gateway.

Equiinet Solution: Through the SIP protocol, Huawei UA5000 + IAD gateway is connected with SINA system to ensure communication between devices.

The final result:

(1) The analog phones of Huawei UA5000 can not only call SINA extensions but also make incoming and outgoing calls.

(2) The analog phones of IAD gateway can be registered on the SINA system. Not only can call each other, but also make incoming and outgoing calls.

Demand 4: According to needs of own business, CSATC wants to do some customized function development.

Equiinet Solution: SINA has perfect communication functions and rich API interfaces to satisfying daily office communication of users and support customized development of new functions.

Notice : business partners who wanna buy our SINA system in the future, they will be able to use all the newly developed features for free.

Summary of customized development requirements of the CSATC:

1. Call Limit Group

Since the CSATC has to manage several subordinate units, the communication systems of these units are all provided by CSATC, so they need to do company-to-company, department-to-department isolation. The call limit group will be set for the companies or departments that are not related to each other.

Scenario description:

(1) In each call limit group, extensions can be specified, eg 1001 1002, the prefix of the number that restricts the number that can't be called, eg 01XXXXXXXXXX, 02XXXXXXXX.

(2) Then 1001 and 1002 can not call 01XXXXXXXXXX and 02XXXXXXXX, other extensions not in the limit group such as 1003, 1004 can call.

2. Caller ID

Scenario Description:

In SINA system, If we turn the Caller ID setting on, it will show the Caller ID. If off, it will not show.

For example, if you turn on the Caller ID on extension 1001, then 1005 calls 1001, 1001 will ring and see the caller ID as 1005.

If you turn off the Caller ID on extension 1001, and then 1005 calls 1001. The Caller ID on 1001 will display as anonymous.

3. Determine whether the number exists

Scenario Description:

If the extension number on SINA is 121X and the extension number on the original system is 122X. Configure 122X routing on SINA and send it to the original system.

The final result:

1213 calls 1211, then it is determined that 1211 is on SINA, then 1211 rings.

1213 calls 1221, then it is determined that 1221 is on the original system. This call will be sent to the gateway to the original system.

4. Feature codes

Scenario Description:

The customer can customize any functions to start or end with *#. For example, *57*1001# sets the call forward to 1001.
