Overture 140 and 180

Overview

The Overture 140 and Overture 180 are tailored to help providers reach their off-net customers and reduce service fees at the same time. The Overture 140 offers highly manageable 10/100 customer access and up to four T1/E1s (eight T1/E1s for the Overture180) for the network connection. These T1/E1s are bonded using either the standard Multilink Point-to-Point Protocol (MLPPP) or PDH Virtual Concatenation (VCAT), offering up to 12 Mb/s (T1) or 16 Mb/s (E1) of service.

Feature Benefit
'Plug-and-play'  platform and design
Compact design makes it simple to install at the customer premise, either as a wall-mounted or rackmounted
unit
Robust management
Allows for easy access to configure or disable access and ports from anywhere; secure in-band
management access from anywhere on the network
L2+ Classification
Customer traffic classification, supporting up to 10 traffic rules per device, as well as VLAN
management, traffic queuing, rate limiting,policing and p-bit remarking
Performance and fault management                                                                                                                    
Support for both Layer 1 and Layer 2 performance monitoring statistics, as well as facility alarms available over both the in-band management channel and the local management console port
Built-in loopbacks and a built-in Ethernet port Time Domain Reflectometer keep service calls to a minimum

 

Overture 140M and 180M Feature Benefit
Multilink Point-to-Point Protocol (MLPPP)   
Bonds from 1-8 T1/E1s to provide bandwidth ranging from 1.5 Mbps to 16 Mbps; automatic removal /
restoration of failed links
Single Link PPP Provides protocol flexibility and interoperability benefits

 

Overture 140V and 180V Feature Benefit
Plesiochronous Digital Hierarchy/Virtual concatenation (PDH/VCAT) Generic Framing Protocol (GFP) Bonds from 1-8 T1/E1s to provide bandwidth ranging from 1.5 Mbps to 16 Mbps; automatic removal/restoration of failed links

 

Applications

Carrier Ethernet Services over Any Infrastructure

  • Carrier Ethernet over T1/E1 and bonded T1/E1
  • Delivers a revolutionary way to reach 90% more customer locations with Ethernet services
  • Uses existing T1/E1 facilities and reduces leased access service fees
  • Standard MLPPP or PDH/VCAT bonding allows T1s/E1s to be added as bandwidth needs grow
  • Perfect for point-to-point and hub-and-spoke deployments
  • Plug-and play design — easy to configure; easy to manage
  • NEBS 3 certified

Most carriers today can deliver Ethernet services to their "on-net" customers where there are fiber drops from existing network infrastructures. However, only 15% of all US businesses today are reachable via fiber, while the remaining 85% are reachable only by copper (T1 or E1 connections). The Overture 140 and 180 are tailored to reach off-net customers easily and economically using existing T1/E1 lines. The Overture 140 offers highly manageable 10/100 customer access and up to four T1/E1s (eight T1/E1s for the ISG 180) for the network connection. These T1/E1s are bonded using either the standard Multilink Point-to-Point Protocol (MLPPP) or PDH Virtual Concatenation (VCAT), offering up to 12 Mb/s (T1) or 16 Mb/s (E1) of service. Additional lines can be added as necessary, and with a simple-to-use Graphical User Interface (GUI), provisioning new circuits has never been easier.

  • The Overture 140 and Overture 180 offer a full complement of management tools that makes it easy to manage and diagnoses network issues. The management tools  including remote loopback testing, as well as cable integrity testing to determine if subscriber-facing Ethernet ports or cables have failed. This allows providers to respond quickly to failures by taking faulty links or ports out-of-service remotely and restoring them when the fault is cleared. The result is significant savings from having to make costly truck rolls to each location for every fault.  SLA monitoring is also supported through the Service OAM (802.1ag and Y.1731) capabilities of the Overture 140 and 180.
