  • Page 21: Configuration Overview

    When the entity is in a no shutdown state (administratively enabled), then the entity is considered to be provisioned. Alcatel-Lucent routers provide the capability to configure chassis slots to accept specific line card and MDA types and set the relevant configurations before the equipment is actually installed. The preprovisioning ability allows you to plan your configurations as well as monitor and manage your router hardware inventory.

  • Page 22: Mcms

    A preprovisioned MDA slot can remain empty without conflicting with populated slots. Up to six MDAs may be provisioned on a 7750 SR-c12. Even numbered slots are invalid for MDA installation (MDAs physically span 2 slots; “mda 1” spans slots 1 and 2).

  • Page 23: Cmas

    (Media Dependent Adapter). 7750 SR-c12 and SR-c4 systems accept CMAs. Up to eight CMAs may be provisioned on a 7750 SR-c12, and up to 4 CMAs may be provisioned on an SR-c4. Up to four CMAs may be provisioned on a 7710 SR-c4. CMA output displays a “c” in the name of the card.

  • Page 26: Oversubscribed Ethernet Mdas

    Oversubscribed Ethernet MDAs Oversubscribed Ethernet MDAs The 7750 SR and 7450 ESS support oversubscribed Ethernet MDAs. These have more bandwidth towards the user than the 10 Gbps capacity between the MDA and IOM. A traffic management function is implemented on the MDA to control the data entering the IOM.

    OC-12/STM-4 SFP small form factor pluggable (SFP) module. The same SFP optics used on Alcatel-Lucent’s SONET/SDH cards can be used on the channelized OC-12/STM-4 MDA. Each channelized OC-12/STM-4 supports 512 channels with DS-0 timeslots that are used in the DS-1/E-1 channel-group.

  • Page 29: Channelized Choc-3/Stm-1 Mda

    Each port for the channelized ASAP OC-3/STM-1 MDA supports channelization down to DS-0 and accepts one OC-3/STM-1 SFP small form factor pluggable (SFP) module. The same SFP optics used on Alcatel-Lucent’s SONET/SDH MDAs can be used on the channelized ASAP OC- 3/STM-1 MDA.

    The channelized OC-3/STM-1/OC-12/STM-4 CES MDAs (c1-choc3-ces-sfp / m1-choc3-ces-sfp, m4-choc3-ces-sfp, m1-choc12-ces-sfp) provide an industry leading consolidation for DS-1, E-1 and n*64kbps for CES. The CES MDAs are supported on IOM-2 and IOM-3XP in the 7750 SR. The channelized OC-3/STM-1/OC-12/STM-4 CES CMA/MDAs support CES. Circuit emulation services are interoperable with the existing 7705 SAR and 7250 SAS circuit emulation services.

    On the 7750 SR-c12 CES CMA, a BITS port is also provided. The BITS port can be configured as one reference sources (ref1, ref2) in the system timing subsystem.
