2.0 Mb PRI hardware requirement (Part 2 of 2)
Circuit card
NTAK93
NTBK51
One of the following cables is required for a PRI connection:
• CEPT Cable - NTBK05DA (120 ¾ twisted pair—6.15 m length), or
• CEPT Cable - NTBK05CA (75 ¾ coaxial—6.15 m length)
Two PRI cards are available on the system:
• NTAK79 2.0 Mb PRI card
• NTBK50 2.0 Mb PRI card
The difference between the two PRI cards is that the NTBK50, when
equipped with the NTBK51 D-channel daughterboard, can download
software onto the card. This feature is based on the MSDL platform and
essentially replaces the D-channel circuit on the NTAK79 PRI card. (The
NTAK79 PRI card does not support the NTBK51 Downloadable D-channel
handler daughterboard.)
