1 Product Orientation1.1 Huawei USC Solution

In recent years, the telecommunications industry has witnessed the change of the simplex

business model to diversified business models. Carriers are exploring new ways to accelerate

growth. The growth in the business, however, is restricted by the following factors:

The subscriber data is distributed among different functional entities using different datamanagement mechanisms. This leads to isolated information "islands" and also requires

complex network structure. It poses a challenge for carries in developing and providing

value-added services.

The equipment used on the legacy network has drawbacks such as small capacity andpoor integration. It cannot keep pace with the rapid growth in subscriber base.

Today, more and more carriers are realizing the importance of convergence and centralized

management of subscriber data. Centralized network rollout and subscriber data convergenceare the emerging trends in the telecommunications industry.

Huawei Unified Subscriber Center (USC) incorporates the functions of network entities such

as the HLR, HSS, and AAA. It can converge the subscriber data required by the NEs in thepublic land mobile network (PLMN), public switched telephone network (PSTN), broadband

network, and multimedia network.

The USC can realize centralized management of the subscriber data and provide open data

interfaces. It can simplify network deployment, accelerate the provisioning of new services,and promote service innovation. The USC solution helps carriers to provide competitive

integrated services.

Lowest accuracy: the maximum frequency offset in a long period (20 years) when the externalreference frequency is unavailable (when the clock works in free-run mode)

Maximum frequency offset: the maximum relative difference between the clock frequencies in one

unit of time during the continuous running of the clock

Pull-in range: the maximum bandwidth of the input signal that the clock system can locks

MRTIE: maximum relative time interval error, the variation of maximum peak-to-peak delay of a

tested clock relative to an actual reference clock within the test time

times sound interval

If the system can still work normally when the jitter frequency of an input signal is 1 kHz and

the signal amplitude is more than 1.5 UI, you can infer that the input signal satisfies

requirements.

UI stands for unit interval. The reciprocal of the digital signal frequency is one UI. For example, the UI

of a 2.048 Mbit/s signal is 488 ns.
