Analyze the market development status of user switches

User switches are worth learning a lot. Here we mainly introduce the market development status of user switches. user switches are an integral part of the national communication network, however, for various reasons, a user's vswitch sometimes fails to provide its effective functions well. One of the most prominent problems is that when a user on a vswitch extension calls a digital pager, the number displayed on the pager is the outgoing relay Number of the User Switch. Because the outbound relay is one-way, only outgoing and inaccessible, the pager user cannot call back.

When a user calls a digital pager, the user can only add a relay number and an extension number. This call method is at least 16 digits, which is inconvenient to use. If the trunk lines are both bidirectional and double-stranded locks, the above problems will not occur, but now more than 100 switches, divides the trunk lines into single-in and single-out channels. When the user switches out of the trunk lines one-way at the local end, the Municipal users hear the blocking sound. Currently, most people cannot tell the blocked voice and busy voice. They treat the blocked voice as a busy voice and call back with great effort, causing unnecessary call loss. When the user switch relay is one-way and the local switch is two-way, the user may hear the blocked sound sent by the user switch, or the return tone of the local switch may be different because of the switch design, but cannot be connected.

In another case, call loss occurs. That is, although the User Switch relay direction is two-way, but the call loss also occurs when the local port is not set to be selected. Because when you use a relay, for example, the first relay, call a digital pager, and then hook up and wait for a call back, if someone else occupies the first relay, A pager user cannot call a phone number before the first relay is released. To call back, the pager user will call the phone number several times until it is connected. Therefore, unnecessary call loss occurs. In order to overcome the above problems, we negotiated with the local telephone Bureau the year before and changed the outbound direction of the original relay ticket to two-way. In addition, all the relay have been connected and selected to ensure smooth telephone communication, this minimizes call loss.

The second problem is that some user switches are occupied by the first relay instead of loop operations, the second user occupies the second set ,....... The utilization of the first few sets of outbound relay is high, and the utilization of the last few sets of outbound relay is low, resulting in uneven utilization of the User Switch's outbound relay and local device.

The third problem is that many manufacturers now configure computer operators on user switches. Although this reduces the labor intensity of operators, there are also some problems. That is, when a local user calls an extension of a user's vswitch, if another municipal user also calls the extension user, the caller should hear a busy or prompt, however, some user switches do not have any sound at this time, and the user has a lot of comments. In addition, when the municipal user directly dials the User Switch extension, the extension must be switched on after the computer voice ends. Otherwise, direct dialing fails. A relay board generally has four or eight relay sets, and the voice circuit assigned to each relay board is only one. When several municipal users call in at the same time, the speech circuit queuing occurs, the time for each computer voice prompt is 5 ~ 8 s. It is a waste of time to wait more than 20 seconds for 4th local users. If you can directly dial the extension before the computer voice ends, the queuing time can be reduced. The fourth problem is that there are several problems in billing management:

1) Calculate the call time. Some calls are calculated in seconds, while others are calculated in minutes. If it is calculated by minute, two calls will start at the same time within one minute, or the same end time will not be delayed billing, but will reverse billing ). The user is often skeptical when querying the phone bill, so it should be accurate in seconds.

2) because the original bill is charged at 30% from seven o'clock to, there is no discount for the original international phone number. Now there is a preferential price and a better discount for neighboring countries, as a result, the original billing standard software management system cannot adapt to the current billing management, so various manufacturers have to consider this aspect. In addition to setting up the automatic discount function, the software management system of the billing standard should also set up the preferential price function manually, because the Spring Festival is calculated based on the calendar and is different every year, you have to consider holidays in some regions.

3) Some manufacturers do not consider non-charged special bureaus, such as 110,119,120,122), and the phone bill is not counted. Therefore, various manufacturers should comprehensively consider the telephone bill Management System for Special bureaus. For billing items and non-billing items, the total score is 1 minute and 3 minutes. For example, 114,184,200,800,108 is calculated by 3 min each time, while 168 is calculated by 1 min. The fee is also different from the four digits after 168, which is generally divided into 0.00 RMB per minute for free ), 0.10 yuan, 0.20 yuan, 0.30 yuan, 0.40 yuan, 0.50 yuan, O.60 yuan, 0.70 yuan, 0.80 yuan. Because the local standards are different, these parameters should be set by the user.

The fifth problem is that most user switches generally have six or eight user levels: no restrictions, international restrictions, international and domestic restrictions, international and domestic suburbs, international and domestic suburbs and local calls, information platforms, and all restrictions. At present, the domestic network is basically implemented in various regions across the country. If the user requires to restrict access outside the province or outside the local network, the user requirements cannot be met. Therefore, the user level should be further subdivided, to meet user requirements.
