MINI-LINK CN 1010 is a Cost effcient and Compact Mobile Backhaul Gateway that  focuses on aggregating Ethernet and TDM traffic from multiple generation RBS’s into an optical packet network.
.It provides Ethernet aggregation and P2P fiber backhaul at non microwave sites, with circuit emulation of TDM traffic.


MINI-LINK CN 1010 is ready for deployment in all wireless mobile
network Generations, 2G, 3G and 4G!



RBS interface and demarcation point
As a Mobile Backhaul Gateway MINI-LINK CN 1010 is located at the edge of the Mobile transport network interfacing directly to the Radio Base Stations; providing backhaul
transmission for existing and future bandwidth demanding mobile broadband services.

MINI-LINK CN 1010 provides E1/DS1 emulation at the backhaul interface for 2G networks and Fast Ethernet/Gigabit Ethernet for 3G/ 4G backhaul. The backhaul service is supported by MEF-defined Ethernet virtual connections: point-to-point E-Line and multipoint-to-multipoint E-LAN services.

MINI-LINK CN 1010 serves as both a circuit emulation  gateway, and as a pure demarcation point. The device enables the separation of different network segments as well as different business responsibility areas.

MINI-LINK CN 500 and the future MINI-LINK 70/80 GHz outdoor GbE radio can also be enhanced by MINI-LINK CN 1010. It then provides the addition of Circuit Emulation Services, Multiple Ethernet ports and Service OAM.



Ethernet switching
The integrated non blocking Gigabit Ethernet switch (IEEE 802.1Q and 802.1ad compliant) has a switching capacity of 8 Gbps Full duplex. Ethernet Protection MINI-LINK CN 1010 offers multiple protection options like LAG (802.1AX Link Aggregation), Ethernet Ring Protection (ITU G.8032v2) and RSTP/MSTP.

Quality of Service
Service differentiation (802.1 p-bits) and traffic separation (VLAN) together with 8 priority queues and traffic scheduling makes MINI-LINK CN 1010 prepared for diverse QoS configurations. The QoS is Ethernet, IP and MPLS aware. MINI-LINK CN 1010 provides Carrier Grade QoS functions like SPQ, WFQ, WRED and Policing.

Both ingress and egress Policing are available for configuring Service Levels that enable network carriers to provide end-to-end guaranteed bandwidth and service level agreements.

Connection-oriented logical flows can be established with MEF 10.1 defined Service Attributes: Committed Information Rate (CIR), Committed Burst Size (CBS), Excess Information Rate (EIR), and Excess Burst Rate (EBS). The attributes are  configurable per flow.


Virtual LAN (VLAN)
MINI-LINK CN 1010 supports VLAN tagging (IEEE802.1Q) and Provider Bridge (802.1ad).

Ethernet OAM
As part of end-to-end network solutions, MINI-LINK CN 1010 complies to Link OAM
(IEEE 802.3ah) and Ethernet Service OAM FM (IEEE802.1ag); together with Ethernet Service OAM PM (ITU-T Y.1731).

Circuit Emulation Service
MINI-LINK CN 1010 provides circuit emulation services for legacy E1/DS1 TDM interfaces. The SAToP (Structure Agnostic TDM over Packet) emulation method disregards any structure that may be imposed on the data stream; e.g. the standard framing as defined in ITU-T G.704.

The emulation endpoints do not interpret the TDM structure nor participate in the TDM signaling. The CESoPSN (Circuit Emulation Service over Packet Switched Network) emulation is a structure aware Pseudowire encapsulation method.

The ITU-T G.704 TDM structure can be identified, and recreated at the remote end. MINI-LINK CN 1010 is hence well equipped to cater for the needs of different network technologies and CES head-end requirements.

Clock Synchronization

MINI-LINK CN 1010 has a comprehensive range of synchronization possibilities.

This makes it prepared for a variety of synchronization scenarios.

The Gateway allows different clock sources:
  • Synchronous Ethernet, (ITU-T G.8261/G.8262/G.8264) • Precision Time Protocol, PTP, (IEEE 1588v2 client)
  • Adaptive clock recovery based on the RTP packet stream from the Packet Switched Network (PSN).
  • E1/DS1 Line clock
  • Local clock
MINI-LINK CN 1010 furthermore provides a separate 2 MHz clock input and output sync port, as well as a sync port dedicated for TDD base station sync requirements, such as Time Of Day (TOD) and 1pps input.

IP multicast
MINI-LINK CN 1010 supports multicast streaming by use of IGMP v2/v3 (Internet Group Management Protocol) snooping.

Alarm Interface

The alarm interface of the MINI-LINK CN 1010 provides four alarm inputs together with two alarm outputs.

Management

Management is handled by ServiceOn EM. Local management can be performed by either using the Local Craft Tool (LCT) or a Command Line Interface (CLI).

Cooling
MINI-LINK CN 1010 comes with a front-mounted fan unit. The fan unit can be replaced without traffic interruption.

Power
Power is supplied by -48 V DC through dual fuse protected power inlets.Subrack solutions MINI-LINK CN 1010 is ready for wall-mounting or installation in 19”/ETSI racks.
