Managing Connections
 |
Note: Connection profiles control services provided on Ethernet subscriber lines. These profiles apply to all Tellabs 1100 Series OLT. |
For information about applying the Connection Profiles to subscriber lines and service connections (cross-connections), refer to:
- Managing Data and Voice Cross-Connections
- Managing Data and Voice Subscriber Lines
Overview
Connection Profiles control fundamental service attributes for DSL and Ethernet cross-connections, such as Service Type, VLAN priority, and rate information. Connection Profiles are stored on the Panorama PON server and at those devices that have cross-connections associated with a profile. The following topics are covered in this section:
- Supported Equipment Applications
- Supported Service Types for Data Connections
- Rate Shaping Behaviors
Supported Equipment Applications
This section summarizes Optical LAN OLTs and the applications supported through Panorama PON. Tellabs 1134/, and Tellabs 1150 Optical LAN OLTs support Ethernet and VoIP services either directly to a Softswitch to a traditional TDM switch.
Supported Service Types for Data Connections
This section summarizes the types of data services (Service Types) supported in Panorama PON for the Tellabs 1100 Series Optical LAN NEs. Each of these network elements supports this minimum set of Connection Profile Service Types for data cross-connections:
- IPTV Service Type - supports customers that receive IPTV traffic separately from ISP traffic (This is a separate multicast TV VLAN connection).
- VLAN Trunk Service Type - provides 24 tagged and 1 untagged VLAN and is dedicated to only trunks and no other service types.
Bridged N:N Service Type Configurations
For Tellabs 1134/OLT6, and Tellabs 1150, ONTs can also be configured to support the following additional Service Types: Bridged service, or Bridged + IPTV service.
- Bridged N:N Service - Supports customers that receive standard Ethernet traffic on one virtual local area network (VLAN) connection (separate from multicast) and also allows the OLT to perform standard transparent bridging (IEEE 802.1Q) of traffic at the data link layer (Layer 2 of the OSI model). Support for IPv4 and IPv6 packet types is enabled as well as the option for full transparency to support all frame types.
- Bridged N:N+IPTV Service - Supports customers that receive both ISP and IPTV traffic on one VLAN connection that supports both standard Ethernet traffic and multicast (IPv4 only). This service type allows transparent bridging of the Unicast flow, provides line rate for non-shaped IPv4 multicast channels, and provides rate-limiting for the flooded broadcast traffic.
With the transparent Bridged N:N Service Type configured for a connection, the system supports mixed IPv4 and IPv6 traffic and bridging of the traffic (all Ethertypes) at the OLT between ONT UNIs. (Traffic is hairpinned at the QOIU7 OLT module and does not require an external switch to perform this UNI to UNI bridging.) In addition to switching traffic between any ports, this feature provides flooding of upstream and downstream Multicast, unlearned Unicast, and Broadcast traffic in accordance with standard IEEE 802.1Q frame filtering and forwarding. To protect bandwidth utilization while performing these flooding functions, the OLT provides strict metering of flooded flows and rate limits flooded packets.
With the transparent Bridged N:N+IPTV Service Type, the transparent bridging feature overlays intelligent distribution of IPv4 multicast, such as that used for IPTV, via an active IGMP Proxy Reporting agent.
When this service type is enabled, the flooding of broadcast, multicast, and unlearned Unicast still occurs with rate limiting. However, multicast group addresses that have been joined are forwarded at line rate to the subset of UNIs that have requested membership to that group.
Refer to Table 1 which summarizes the provisionable Service Types for data connections.
Table 1: Data Connection Service Types Summary
| Service Types | Network: Subscriber VLAN Connectivity | Bridging Options | System Behavior Notes |
| Single Service Data Connection Service Types: | |||
| Bridged N:N | N:N | Full Bridging |
|
| VLAN Trunk | 1:N | Full Bridging |
|
| IPTV | 1:N | No Bridging occurs | IPv4 IGMP aware (supports multicast TV) |
| Dual Service Data Connection Service Types: | |||
| Bridged N:N+IPTV | N:N (data) and 1:N (video) | Full Bridging (data) No Bridging (video) |
|
Conditional bridging options combined with Service Type selections for the system allow for optimized bandwidth utilization as well as variable security and traffic control mechanisms. For more information about configuring and provisioning network VLANs and associating them to network uplinks and cross-connects for the system, please read section Managing Network VLANs with VLAN Property and VLAN Assignment.
Multiple data connections (and Service Types) can be provisioned for a subscriber port within limitations. For more information, please review Rules for Data Cross-Connections and Managing Multiple Connections for One Subscriber.
For more information about Service Protocol types (IPoE, PPPoE, etc.) and other definable attributes of the Connection Profile refer to Table 1 Connection Profile Options.
