Patent CA-2260661-A1 (CA)
Title: Mailpiece stacking system and method
Inventor: BROWN MICHAEL A
IPC: B65H31/26
Filed: 1999-02-02
Abstract: In a mailpiece stacking system, a pressure pad is used to direct incoming mailpieces from a mailing machine used with the system onto a feed deck, where the mailpieces are stacked against a stacking wall in the system. To properly handle mailpieces including window envelopes, the length of the pressure pad is selected in accordance with the invention such that it effectively deflects each mailpiece to land beyond the window part of any window envelope preceding thereto on the feed deck.      Advantageously, the risk of having the mailpiece getting caught by an edge of the window part, resulting in a congestion, is avoided. In addition, among other things, a catch nub is included in the pressure pad for hooking onto a stub shaft mounted on the frame of the system. The nub hooks onto the stub shaft when the pressure pad is raised to allow it to stay in the raised position. Moreover, to effectively attach the stacking system to the mailing machine, the stacking system provides thereunder a hook having a C-shaped opening. The hook is used to be slidably engaged with a support knob underneath the mailing machine through the opening. The resulting engagement aligns the mailing machine with the stacking system to allow proper feeding of the mailpieces from the mailing machine to the stacking system, notwithstanding the vibrations occasioned by the operation of the mailing machine and the stacking system.

Abstract: The invention relates to a method for packet transfer in a telecommunications network. In a node (N1) at the boundary of the network, the data packets to be transmitted are segmented into lower protocol layer data units. The data units are transferred in the network both in default channels and in dedicated channels. For efficient routing of the data packets, the node (N1) at the boundary of the network monitors packets that pertain to the same flow, and upon detecting that a given flow meets predetermined criteria, a dedicated lower protocol layer connection identifier is assigned for its use. In a node (N2) within the network, the connection identifiers of incoming data packets are monitored, and upon detection of a new connection identifier that is not associated with a default channel or a dedicated channel, an output port and a new outgoing lower protocol layer connection identifier are defined for the data unit on the basis of the destination address of that packet, and the data unit is routed to the relevant output port. Upon detection of the same lower protocol layer connection identifier as said new connection identifier in subsequently arriving data units, routing is performed in the node (N2) merely on the basis of the lower protocol layer connection identifier. Dedicated connections are discarded from use in the nodes after no traffic in a flow having a dedicated connection identifier has been detected during a given period of time.

Title: Automated private numbering plan provisioning
Inventor: DUMONT JIM
IPC: H04M3/00
Filed: 1998-06-26
Abstract: A method in a telecommunications network having a configuration management system, of automatically populating a Private Numbering Plan (PNP) subscription with PNP  data. The method begins by defining a group comprising a plurality of members who subscribe to a PNP service (5-11), and automatically generating the PNP data for each of the plurality of group members when the group is defined. The PNP data may be generated by service management application software in the configuration management system. The PNP data may include an abbreviated number for each of the plurality of group members.  The abbreviated numbers may be generated by several methods including incremental number generation (5-37), random number generation (5-39), or by extracting the last "X"  digits of each group member's telephone number (5-42). The method then determines whether each generated abbreviated number is valid and unique (5-55). A  network operator may override an automatically generated number by manually inputting an abbreviated number which is valid and unique (5-57).
