In-service upgrades

Overview

This section briefly describes the in-service network, optical span, and node upgrades supported for Alcatel-Lucent 1665 DMX.

In-service high-speed OC-48 UPSR to OC-192 UPSR upgrade

Alcatel-Lucent 1665 DMX supports an in-service upgrade, enabling you to increase UPSR network capacity from OC-12 to OC-48 (12 STS-1 [small] fabric packs or STS-48 [medium] fabric packs).

In-service high-speed OC-48 BLSR to OC-192 BLSR upgrade

Alcatel-Lucent 1665 DMX supports an in-service upgrade, enabling you to increase BLSR network capacity from OC-48 to OC-192 without affecting service.

In-service OC-12 UPSR to OC-48 UPSR upgrade

Alcatel-Lucent 1665 DMX supports an in-service upgrade, enabling you to increase UPSR network capacity from OC-12 to OC-48 (small, 12 STS-1 fabric packs) without affecting service. In-service network upgrades to the LNW82 are not currently supported

In-service 1+1 upgrade

Alcatel-Lucent 1665 DMX supports an in-service upgrade, enabling you to increase 1+1 network capacity from OC-3 to OC-12or OC-12 to OC-48 (Main and tributary packs) without affecting service.

In-service protected OC-n to DWDM span upgrade

Alcatel-Lucent 1665 DMX supports an in-service upgrade to add DWDM Optical Multiplexer/Demultiplexer (OMD) circuit packs into the optical span, thereby increasing the transmission capacity of the optical span. The original OC-n signal is carried in one of the OMD channels and the remaining OMD channels are available to carry additional service. To insert the OMD circuit packs into the optical span in-service requires that the span be either 1+1 protected or be part of a UPSR/BLSR ring.

In-service LNW1 to LNW2 node upgrade

The LNW1 is not supported by the current Alcatel-Lucent 1665 DMX release. An in-service upgrade from the LNW1 to LNW2 can be performed on any shelf that is running Release 5.1 software. The LNW1 functions with every software release prior to R6.0, but the LNW2 must be used with R6.0 or later releases.

In-service high-speed OLIU circuit pack upgrades

Alcatel-Lucent 1665 DMX supports the following in-service high-speed OLIU circuit packs upgrades:

• Small fabric LNW26B, LNW28, LNW77 OC-48 OLIUs to large fabric LNW27, LNW29, LNW32, LNW76, or LNW202, OLIUs

• Large fabric LNW27, LNW29, LNW32, LNW76, or LNW202 OC-48 OLIUs to Very Large Fabric (VLF) multirate LNW82 OC3/OC12/OC48 OLIUs

• Large fabric LNW27, LNW29, LNW32, LNW76 or LNW202 OC-48 OLIUs to Very Large Fabric (VLF) LNW59 OC-192 OLIUs via LNW56 OLIU. This is a one step upgrade that just needs the LNW56 in one node.

• Large fabric LNW56, LNW57 (DA'd September 2011), LNW58, LNW502, or LNW555 OC-192 OLIUs to Very Large Fabric (VLF) LNW59 OC-192 OLIU

• Very Large Fabric (VLF) multi-port, multi-rate LNW82 OLIU to Very Large Fabric (VLF) LNW59 OC-192 OLIU (one port)

• Large fabric LNW56, LNW57 (DA'd September 2011), LNW58, or LNW502 OC-192 OLIUs to Very Large Fabric (VLF) LNW504 OC-192 OLIU

• Very Large Fabric (VLF) LNW59 OC-192 OLIUs to Very Large Fabric (VLF) LNW504 OC-192 OLIU (one or two port)

• Small fabric LNW48, LNW50, LNW54, LNW203 OC-12 OLIU to a single OC-12 port on the Very Large Fabric (VLF) multi-port, multi-rate LNW82 OLIU

In-service low-speed OLIU circuit pack upgrades

Alcatel-Lucent 1665 DMX supports the following in-service low-speed OLIU circuit packs upgrades:

• low-density 4-port LNW36/LNW37 OC-3 OLIU to high-density 8-port PTM-based LNW45 OC-3 OLIU

• LNW36/LNW37/LNW45 OC-3 OLIU to 12-port PTM-based LNW55 OC3/OC12/OC48 OLIU

• low-density 2-port LNW46 OC-12 OLIU to high-density 4-port PTM-based LNW49 OC-12 OLIU

• LNW46/LNW49 OC-12 OLIU to 12-port PTM-based LNW55 OC3/OC12/OC48 OLIU

• 1-port LNW31 OC-48 OLIU to 12-port PTM-based LNW55 OC3/OC12/OC48 OLIU

In-service PTM upgrades

Alcatel-Lucent 1665 DMX supports in-service, per port upgrades of the OC-3, OC-12, OC-48 PTMs on the multi-port, multi-rate LNW82 and LNW55 circuit packs.

In-service electrical upgrade from low to high-density DS1/DS3 circuit packs

Alcatel-Lucent 1665 DMX supports an in-service electrical upgrade on the High-Capacity shelf, enabling you to increase DS1/DS3 capacity without affecting service. There is an outage of 100 to 200 milliseconds when upgrading DS1 circuit packs. By upgrading the 28-port LNW7 to the 56-port LNW8 or LNW801, the total DS1 capacity is increased from 112 to 224 DS1 interfaces per shelf.

By upgrading the 12-port LNW16 to the 48-port LNW19B/20, the total DS3/EC1 capacity is increased from 48 to 192. Electrical in-service upgrades can be performed on shelves hosting a mix of DS1 and DS3/EC1 circuit packs without affecting service. The Alcatel-Lucent 1665 DMX High-Capacity shelf is required when using high-density DS1/DS3 circuit packs.

The LNW16, LNW18, LNW19/19B, can be upgraded in-service to the LNW20.

LNW70 to LNW170 circuit pack upgrade

Alcatel-Lucent 1665 DMX supports upgrading an unprotected LNW70 (DA'd January 2010) circuit pack to an LNW170 circuit pack in the same slot. Since the LNW70 circuit pack cannot be protected, this is not an in-service upgrade. However, this upgrade can be performed without removing cross-connections or other provisioning. The LNW170 circuit pack supports all the functionality of the LNW70 circuit pack and adds equipment protection.
