2.5 High

Speed

Access

Interface

ZXMSG 5200 supports GPON/EPON line card and VDSL2 (30a profile) line card.

2.5.1 VDSL2 access solution

VDSL2 (Very High Speed Digital Subscriber Line 2) is an access technology that exploits the existing infrastructure of copper wires that were originally deployed for POTS services. It can be deployed from central offices, from fiber-fed cabinets located near the customer premises, or within buildings. The greater bandwidth of VDSL2 gives telecommunications operators the ability to offer advanced services such as multiple streams of interactive standard and high-definition TV over IP over the existing copper plant. TV services are fast becoming strategically important to telecommunications operators who must now compete head-to-head with cable operators launching voice over IP (VoIP) and high-speed internet services.

Many operators have thus already started to consider fiber deeper into the access network – for example, fiber to the node (FTTN) and fiber to the curb (FTTC) – shortening the length of copper loops to less than 1500 meters.

The VDSL2 line card in ZXMSG 5200 supports all the VDSL2 features, such as lower power consumption, convenient VDSL2 management interface, fully TR101 compliant, high performance, and better interoperability.

2.5.2 xPON access solution

PON technology supports services such as voice, data and video for network construction, on the other hand, PON provides symmetrical high bandwidth for both upstream and downstream (EPON upstream 1.25G bps, downstream 1.25G bps, GPON upstream 1.25G bps, downstream 2.5G bps), with passive splitter and single mode fiber, EPON is easy for management, maintenance, and can greatly reduce CAPEX and OPEX of network.

Fiber access is one of the key technologies of Next Generation Network (NGN). FTTx (x can be Home, Business/Building, Cabinet network or other fiber applications) meets the requirements of the Access Network (AN). PON technology uses passive ODN equipments, which are small in size with less electromagnetism disturbance and fault rate. The long distance (i.e. 20 Km) between OLT and ONU meets multiple users’ requirement. Passive ODN makes network much easier for management and maintenance. The life of optical fiber is more than 50 years, much longer than that of normal copper cable. FTTx solutions based on PON technology are becoming more and more popular in world wide.

For ZXMSG 5200, the support of EPON/GPON line card can match the requirement of some enterprises and family, which need more bandwidth. ZXMSG 5200 can provide the access solution, not only in copper access, but also in fiber access.

(13)

ZXMSG 5200 supports 1 EPON interface each EPON line card, and 4 GPON interfaces each GPON line card.

2.6 High Speed Uplink Interface

The GISX board provides two 10GE optical ports for uplink. The EPNI card provides one EPON uplink interface.

With the development of different broadband service, especially services based on video and audio, such as IPTV, video conferencing, on line gaming, HDTV etc, the bandwidth requirement is becoming higher and higher. The bandwidth requirement for these services ranges from 20 ~ 50Mb/s even up to 100Mb/s.

ZXMSG 5200 provide several options to choose for uplink interface, such as GE, EPON, and 10GE. The EPON interface is used in FTTB/FTTC scenario, where 5200 acts as ONU. The GE/10GE interface is used in FTTN scenario; where 5200 is deployed at CO. Carrier choose different interface, according to the bandwidth requirement, and fiber development strategy. With 10GE slot bandwidth, ZXMSG 5200 support 10GE line speed.

(24)

3.1.4 Voice Quality Techniques

ZXMSG5200 ensures voice service quality through:

• Supports the echo cancellation function meeting the G.165/G.168 requirements • Supports the VAD (voice activity detection) function

• Supports the CNG (comfort noise generation) function • Supports Packet Loss Concealment (PLC)

• Jitter buffer dynamic adjustment • Tx/Rx gain control

• Differentiated priority & SLA calls. ZXMSG5200 can support service priority based on physical port or emergency number (such as 110, 119 etc) to guarantee better quality for higher priority service.

− Physical port priority: VIP customer port is set higher priority while ordinary customer port is set lower priority so the ordinary customer will get busy tone in case of traffic congestion.

− Emergency number priority: No matter from VIP or ordinary customer, emergency call always can call successfully even when MSAN is overloaded. ZXMSG5200 also adopts the following measures to separate VoIP stream and broadband stream to grantee the voice service quality:

• Different VLANs for VOIP media, signaling, management, broadband stream

• Different Class of Service (CoS) value for VOIP media, signalling, management, broadband stream

MPR ICS upper sub-card

ZXMSG 5200 working principle is as follows:

• Narrowband traffic from POTS interface enters TDM switching module of main control card (i.e. ICS).

• TDM switch performs circuit-switching on the voice signals and send them to voice compression module.

• MPRB board which performs voice compression function converts voice traffic into IP packets and send them to Ethernet switching module.

• Ethernet switching chip switches the IP packets and send them to CNIC sub-card for network address translation.

• After network address translation, IP packets enter the IP network through an uplink interface after Ethernet switching.

• Broadband data from xDSL or xPON interface enters main control card Ethernet switching chip and directly goes to IP network through an uplink interface.
