The information in this section describes how TDM hardware is migrated and reused in the Device Adapter environment.
Opt 81C / Opt 51C / Opt 61C / CS 1000M
MGC-hosted cabinets replace EPE modules.
IPE modules are reused.
NT8D01 XPEC controller card is replaced by MG-XPEC NTDW20 card.
MG-XPEC converts the IPE module into two Media Gateway shelves.
The MG-XPEC card can be thought of as two separate MGCs bolted together with the left board (motherboard) controlling the left half of the of the IPE shelf and the right (daughterboard) controlling the right half of the IPE shelf.
NT8D21 ring generator is reused.
IPE Line ALC and DLC cards are reused.
Non-IPE Line ALC and DLC cards are replaced by IPE ALC and DLC cards.
Other IPE cards (such as TDS, DTR, and XUT) are not reused.
MC32 and MC32s cards are not reused.
CLASS Modem cards are not reused. Instead, the DSP that is assigned to the CLASS set for voice traffic handles the necessary function, such as, modulate the caller’s name and number.
Opt 11
NTAK11BD, NTDU14CA, and NTDU14CB cabinets are reused.
The SSC is replaced with an MGC (NTDW60 and NTDW98) card with one or two DSP DB NTDW78.
The number of required DSP DBs depends on DSP capacity engineering rules.
IPE Line ALC and DLC cards are reused.
Other line cards are not reused.
CLASS Modem cards are not reused. Instead, the DSP that is assigned to the CLASS set for voice traffic handles the necessary function, such as, modulate the caller’s name and number.
CS 1000E
All cabinets are reused.
MGC controller (NTDW60 and NTDW98) is reused.
It might be required to replace old DSP daughterboards with DB128 to provide higher DSP capacity to serve more endpoints. Refer to the capacity calculation rules below.
CPMG cards must be replaced by NTDW60 and NTDW98 MGC controllers.
IPE Line ALC and DLC cards are reused.
Other line cards are not reused.
MC32 and MC32s cards are not reused.
CLASS Modem cards are not reused. Instead, the DSP that is assigned to the CLASS set for voice traffic handles the necessary function, such as, modulate the caller’s name and number.
