provides A and B inputs, which may be independently configured, but only one may be
active at a time.
3.14 Quad Input DVB-S/DVB-S2 with LNB – Option 8716/8716G
This card will input a satellite L-band (950 MHz – 2150 MHz) signal for demodulation of
KU-band or C-band DVB-S QPSK signals or DVB-S2 QPSK/8PSK signals. The symbol
rate ranges from 1 MSym/s to 45 MSym/s for both DVB-S and DVB-S2. This card
provides LNB power and 22 kHz control tone to the active input. This card has advanced
feature options of multistream input, support for VCM, and support for 16APSK and
32APSK modulation. The “Input” LED will only illuminate if the card detects frequency,
symbol rate, FEC lock (Carrier Lock), and TS sync (Sync Lock). The card provides A, B,
C and D inputs, which may be independently configured, but only one may be active at a
time.
3.15 CAM Decryption – Option 8721
This is a factory installed slot that will allow for up to two CAM cards to be installed at a
time, giving the MRD 3187B the ability to decrypt Conditional Access transport streams.
This card also includes all the functionality of the 8722 option card as well.
3.16 Backup Network Controller – Option 8724
This is a factory installed option into slot 1-4, giving the user the ability to control the
MRD 3187B through a secondary network controller card.
3.17 MPEG over IP Input/Output – Option 8725
This card is a dual purpose card in that it can receive and/or transmit from the internal
TS bus, MPEG over IP. Up to two multicasts can be subscribed to, allowing for a backup
multicast to be chosen and three mirrored multicasts can be transmitted to allow for
redundancy.
3.18 Dual MPEG over IP Input/ UDP Output – Option 8727
This card is a dual purpose card in that it can receive and/or transmit from the internal
TS bus, MPEG over IP. It has two physical connectors that can be configured
independently. Up to two multicasts can be subscribed to, allowing for a backup
multicast to be chosen and two UDP mirrored unicasts can be transmitted to allow for
redundancy
