Signaling for the Star Remote System 3-7 established at provisioning time. Messages over the embedded operations channel (EOC) control the assignment of the D-channel. Communication protocol The host XPM and Star Hub communicate with the SuperNode switch over DS-1 links that terminate on the host XPM. The high level data link control (HDLC) protocol communicates between the host XPM and the Star Hub.
Page 92: Signaling Functions And Capabilities
3-8 Signaling for the Star Remote System Signaling functions and capabilities This section describes the signaling protocols used by the Star Hub to communicate with the DMS SuperNode switch and provide subscriber services. The following paragraphs discuss Star Hub signaling and the types of subscriber services they provide.
Page 93: Star Remote System Service Capabilities
Signaling for the Star Remote System 3-9 Star Remote System service capabilities Star Hub signaling maintains call processing activities by allowing the functions of call origination, tone generation, digit collection, and ringing to occur. The following paragraphs describe each of these activities. Call origination Star Hub and Star Module signaling transmits the on-hook and off-hook signals that allow the host XPM to identify subscribers requesting service.
Page 94: Digit Collection
3-10 Signaling for the Star Remote System Digit collection The Star Hub and Star Module perform the digit collection function of subscriber dialing. The Star Hub and Star Module use dial pulse, or DTMF dialing. The address of a called party can be transmitted using dial pulsing or multi frequency signaling.
Page 95: Ringing
Signaling for the Star Remote System 3-11 Ringing The CO determines the type of ringing to apply. The CO sends a ringing signal to the Star Hub over the DS-1 channel associated with the subscriber line being called. This ringing signal tells the Star Hub to connect the ringing generator to that line.
Page 96: Mbs Signaling
3-12 Signaling for the Star Remote System The Star Hub in ESA provides the same tones as a correctly functioning Star Hub. The UMP card provides tone cadence, which interrupts the tone by controlling the RCP card. To provide a tone in ESA mode, the UMP sends a start cadence message to the RCP.

Signaling for the Star Remote System 3-15 XLBUS The DBIC uses a point-to-point connection to each line card to exchange voice and data with the xLCs. The extended LBUS (XLBUS) is bidirectional with a total capacity of approximately 1.5 Mbit/s for data trafﬁc. Upstream data, downstream data, and control data share this capacity.

If the Star Hub detects any faults, the system tests and handles drawers in the ISTb state. The following table lists states for the Star Hub unit and the related tests.
Page 104 4-4 Star Remote System automatic maintenance Each test starts when all previous tests have passed. The following paragraphs describe these four tests. Hardware presence test This test checks for the presence of formatted (NT6X41), message (NTMX76AB), and timeswitch (NT6X44) cards in the LTC.

Page 110 4-10 Star Remote System automatic maintenance Figure 4-2 Power Supply Distribution Detail in STAR HUB The A feed provides a talk battery for Unit 0 of the Star Hub. The B feed provides a talk battery for Unit 1 of the Star Hub. The A feed and B feed each provide power to one NT6X53AA power converter in each unit.
Page 111 Star Remote System automatic maintenance 4-11 conﬁguration provides a redundancy of power from both power feed sources to each unit of the Star Hub. There is also some redundancy. When the talk battery returns, a single fault may not cause an outage. If a talk battery fuse blows, the Star Hub indicates InSv (in service) at the MAP display.
Page 112 4-12 Star Remote System automatic maintenance Diagnostic programs report all talk battery failures when the same Star Hub is tested repeatedly. If the talk battery test passes, the diagnostic programs clear the alarm and ISTb reason. This has an effect on both the manual and automatic versions of these commands.
Page 113 Star Remote System automatic maintenance 4-13 MAP commands that can RTS the ﬁrst available WLC on a Star Hub shelf provide the following notiﬁcation messages. This notiﬁcation message tells operating company personnel the minor alarm and ISTb reason for the Star Hub shelf are cleared.

4-16 Star Remote System automatic maintenance Intraswitching is supported in the Star Hub. When the Hub enters ESA, steady non-ISDN calls that originate and terminate within the Star Remote System are interswitched and maintained during a warm ESA. The Star Module does not support intraswitching or the ESA mode.

For this reason, the drawer state is updated to ISTb at the MAP display, but the drawer is not prevented from handling call processing.

4-18 Star Remote System automatic maintenance • ZERO_CROSSING_INT_SLOW_FAIL • MEMORY_TEST Faults that occur on a BIC drawer have an effect on call processing without regard to which unit is in-service and controlling that drawer. Because the full in-service tests use the DCC, operating company personnel must ﬁrst determine if the fault is not in the DCC where takeover is justiﬁed.
