COMSPHERE 3600 Series Data Service Units6-34 July 1999 3610-A2-GB91-90Table 6-9(1 of 3)TDM Setup (MUX Funct: TDM) Configuration OptionsMUX Funct: TDMNext TDM MCMP CBrdg EBrdg None PrevTDM/MCMP Circuit Card Function with TDM mode selected. Selects the mode of operation for the TDM orMCMP circuit card.TDM — Configures for TDM mode for a point-to-point multiplexing or digital-sharing configuration.MCMP — Configures for MCMP mode for multichannel multipoint operation and digital-sharingconfiguration (only displayed for an MCMP circuit card).CBrdg 1 — Configures for Bridge mode for a central-site bridge configuration.EBrdg 1 — Configures for Bridge mode for a extended bridge configuration.None — Configures for Basic mode, which bypasses the TDM or MCMP circuit card.Share DevA: DisabNext Enab Disab PrevSharing Device A. 2 Enabling this configuration option allows you to create one of two digital-sharing groups.The following rules apply:• All ports in a group must have the same port speed.• All ports must be adjacent.• A digital-sharing group can have from 2 to 6 ports (only 2 ports when a 2-port TDM/Flex is installed).Enab — Enables the digital-sharing feature.Disab — Disables the digital-sharing feature.Lowest Port #: 1Next 1 2 3 4 5 PrevLowest Port Number. Allows selection of the lowest port number to be included in the digital-sharing group.This configuration option is displayed only if Sharing Device A is enabled.1 to 5 — Selects the lowest port number. This configuration option does not appear when a 2-portTDM/Flex is installed.# Ports in Gp: 2Next 2 3 4 5 6 PrevNumber of Ports in Group. Allows selection of the total number of ports to be included in the digital-sharinggroup. This configuration option is displayed only if Sharing Device A is enabled.Enabling Sharing Device A and accepting the defaults for configuration options Lowest Port Number andNumber of Ports in Group places Ports 1 and 2 in the digital-sharing group.Individual ports in a digital-sharing group can be configured for streaming terminal. If streaming terminaldetection is enabled on a port and RTS for that port is ON longer than the value selected for that port, theport’s leads are clamped until RTS is turned Off.2 to 6 — Selects the number of ports. This configuration option does not appear when a 2-portTDM/Flex is installed.1 If a DBM is installed, it must be disabled when the DSU is configured for CBrdg or EBrdg.2 For an LPDA-2 configuration, only Sharing Device A can be used to create a digital-sharing group.
