cables. This card does not accept any trunk daughter cards. A maximum of 1 4–port
expansion base card is allowed per control unit (right-hand slot 4 only). See External
expansion modules on page 22 for a list of the supported external expansion
modules.
- BRI combination card — This card provides 6 digital station ports (1-6), 2 analog
extension ports (7-8) and 2 BRI trunk ports (9-10, 4 channels). The card also includes
10 VCM channels. This card has a pre-installed BRI trunk daughter card. A maximum
of 2 BRI combination cards of any type are allowed per control unit.
- ATM combination card — This card provides 6 digital station ports (1-6), 2 analog
extension ports (7-8) and 4 analog trunk ports (9-12). The card also includes 10 VCM
channels. This card has a pre-installed analog trunk daughter card. A maximum of
2 ATM combination cards of any type are allowed per control unit. The analog phone
ports do not include a ringing capacitor. Where this is a requirement, connection
should be via a Master socket containing ringing capacitors. If fitted with an analog
trunk daughter card, during power failure phone port 8 is connected to analog trunk
port 12.
- TCM 8 card — This card provides 8 digital station ports (1-8).
• Trunk daughter cards — Most base cards can be fitted with a trunk daughter card to
support the connection of trunks to the base card. The following trunk daughter cards are
supported:
- Analog trunk card — This card allows the base card to support 4 analog loop-start
trunks. The analog phone ports do not include a ringing capacitor. Where this is a
requirement, connection should be via a Master socket containing ringing capacitors.
If fitted with an analog trunk daughter card, during power failure phone port 8 is
connected to analog trunk port 12. A maximum of 4 analog trunk cards are allowed
per control unit.
- BRI trunk card — This card allows the base card to support up to 4 BRI trunk
connections, each trunk providing 2B+D digital channels. The card is available in 2
port (4 channels) and 4 port (8 channels) variants. A maximum of 4 BRI trunk cards
are allowed per control unit. For S-Bus connection, the card can be switched from
To trunk mode to So mode. This mode requires additional terminating resistors and
an ISDN crossover cable connection.
- PRI trunk card — This card allows the base card to support up to 2 PRI trunk
connections. The card is available in single and dual port variants. The card can be
configured for E1 PRI, T1 robbed bit, T1 PRI or E1R2 PRI trunks. A maximum of 4
PRI trunk cards are allowed per control unit. The B5800 Branch Gateway system
supports 8 unlicensed B-channels on each IP500 PRI-U port fitted. Additional B-
channels, up to the capacity of ports installed and PRI mode selected require
Universal PRI (Additional Channels) licenses added to the configuration. These
additional channels consume the licenses based on which additional channels are
configured as in-service from port 9 of slot 1 upwards. D-channels are not affected
by licensing.
• Combination cards — Combination cards are pre-paired base and trunk daughter cards.
They provide 6 digital station ports, 2 analog phone ports, 10 VCM channels and either
