Alcatel-Lucent 1665 DMX is designed to provide a vast array of wideband and broadband voice and data services. Therefore, there is great flexibility in the configuration of the shelf. Various combinations of circuit packs may be used for whatever service is desired. The following paragraphs outline the specific packs that may be used in the Function Unit groups for certain applications.
Note:
See Medium and large fabric engineering rules for important information regarding the functioning and capacities of circuit packs.
The SYSCTL LNW2 circuit pack must be located in the control CTL slot.
At least one Main (M1/M2) circuit pack is always required in Alcatel-Lucent 1665 DMX to provide timing for the shelf. M1 and M2 can be equipped with any of the following types of packs:
The Main Switch Pack (LNW80) must be located in the main M1 and M2 slots for protected service.
OC-12 OLIU LNW48, LNW50, LNW54, LNW203 must be located in the main M1 and M2 slots for protected service.
OC-48 OLIUs LNW27, LNW29, LNW32, LNW76, LNW82, LNW202, LNW504 must be located in the main M1 and M2 slots for protected service.
OC-192 OLIUs LNW56, LNW58, LNW59, and LNW502 must be located in the main M1 and M2 slots for protected service
The VLF LNW59, LNW82, or LNW504 OLIU circuit packs are required in the main M1 and M2 slots when LNW55, LNW62, LNW64, LNW603 OLIU circuit packs are installed in the function/growth slots.
The tributary slots (A1, A2, B1, B2, C1, C2, D1, D2, G1, G2) can be occupied by a variety of service interface packs. Refer to Tributary interface circuit packs for a comprehensive list of the tributary circuit packs. The following rules apply to the tributary packs.
The LNW37 and LNW45 (OC-3), LNW49 (OC-12), and LNW31, LNW55, LNW62, LNW402 (OC-48) packs may be used interchangeably.
Except for unprotected applications, the same circuit pack type is required in the service and protection slots of a function/growth group (for example, D1 and D2) and growth slots G1 and G2. When the main slots are equipped with VLF circuit packs, Alcatel-Lucent 1665 DMX supports true 0x1 configurations. Slots 1 and 2 of a group can be equipped with the same circuit pack type or with different circuit pack types (certain restrictions apply). When a companion slot is unoccupied, an apparatus blank must be installed in the empty slot regardless of the software release or the circuit pack types installed in the shelf.
The electrical interface circuit packs (LNW7, LNW8, LNW801, LNW16, LNW18, LNW19B, and LNW20) must be located in function unit slots A - D. Growth slots do not support electrical interface circuit packs. However, when the LNW20 circuit pack is installed in the Growth slots, portless DS3 port operation is supported. LNW7 circuit packs are not supported in shelves equipped with VLF circuit packs.
When non-VLF Main circuit packs are used, the Ethernet circuit packs (LNW63, LNW87, LNW170) must be located in slot 1 of a function unit (including growth slots). The other slot must contain a 177D apparatus blank or an LNW98 detectable blank circuit pack. When VLF Main circuit packs are used, Ethernet circuit packs can be used in both slots of a group. Certain restrictions apply. See Very large fabric (VLF) engineering rules.
Without VLF Main circuit packs, the FC-DATA SAN circuit packs (LNW73/73C) must be located in slot 1 of a function unit (including growth slots). The other slot must contain a 177D apparatus blank or an LNW98 detectable blank circuit pack. When VLF Main circuit packs are used, SAN circuit packs can be used in both slots of a group. Certain restrictions apply, see Very large fabric (VLF) engineering rules.
When VLF Main circuit packs are not used, 10/100T (LNW66) circuit packs must be located in slot 1 of a function unit. The other slot must contain a 177D apparatus blank or an LNW98 detectable blank circuit pack. Growth slots G1 and G2 do not support the 10/100T and 10/100-PL circuit packs.
When VLF Main circuit packs are used, some Ethernet circuit packs can be used in both slots of a group. Certain restrictions apply. See Very large fabric (VLF) engineering rules.
When VLF Main circuit packs are not used, the Fast Ethernet Private Line circuit pack (LNW74) must be located in slot 1 of a function unit. The other slot must contain a 177D apparatus blank or an LNW98 detectable blank circuit pack. The LNW74 circuit pack can be used in G1 as well, but only the optical ports will function (true for all Releases).
When VLF Main circuit packs are used, some Ethernet circuit packs can be used in both slots of a group. Certain restrictions apply. See Very large fabric (VLF) engineering rules.
An apparatus blank (177D or 177E) or detectable blank circuit pack (LNW97 or LNW98) must be used in every unequipped slot.
