摘要： A method of providing restoration routes for protecting traffic in a mesh network is described. The method comprises the steps of generating a set of eligible restoration routes for each span in the network, establishing a bi-criteria objective function in terms of route length and capacity cost for selecting a set of restoration routes, and selecting a set of restoration routes for each span from the eligible restoration routes in dependence upon the bi-criteria objective function. Embodiments of the invention may be useful for shortening the lengths, in terms of hops, of existing restoration routes in a mesh-restorable network and in some cases with negligible spare capacity penalty.

摘要： A method to increase the capacity efficiency of span-restorable mesh networking on sparse facility graphs. The new approach views the network as a “meta-mesh of chain sub-networks”. This makes the prospect of WDM mesh networking more economically viable than with previous mesh-based design where the average nodal degree is low. The meta-mesh graph is a homeomorphism of the complete network in which edges are either direct spans or chains of degree-2 nodes. The main advantage is that loop-back type spare capacity is provided only for the working demands that originate or terminate in a chain, not for the entire flow that crosses chains. The latter “express” flows are entirely mesh-protected within the meta-mesh graph which is of higher average degree and hence efficiency for mesh restoration, than the network as a whole. Nodal equipment savings also arise from the grooming of express lightpaths onto the logical chain-bypass span. Only the meta-mesh nodes need optical cross-connect functionality. Other sites use OADMs and/or glassthroughs. The resultant designs comprise a special class of restorable network that is intermediate between pure span restoration and path restoration. Most of the efficiency of path restoration is achieved, but with a span restoration mechanism which is more localized and potentially faster and simpler than path restoration. The concept lends itself to implementation with OADMs having a passive waveband pass-through feature to support the logical chain bypass spans for express lightpaths.
摘要翻译：一种在稀疏设施图上提高跨度可恢复网状网络的容量效率的方法。新方法将网络视为“链子网络的元网格”。这使得WDM网状网络的前景比以往的平均节点度低的基于网格的设计更经济可行。元网格图是完整网络的同构，其中边缘是二阶节点的直接跨度或链。主要的优点是环回型备用容量仅用于起始或终止于链中的工作要求，而不是跨越链的整个流程。后者的“表达”流在元网格图中完全网格保护，该网格图具有比网络作为整体更高的平均度，因此网格恢复的效率。节能设备的节省也源自于将明快的光线融入逻辑链 - 旁路跨度。只有元网格节点需要光交叉连接功能。其他网站使用OADM和/或glassthroughs。所得到的设计包括一个特殊类别的可恢复网络，其在纯跨度恢复和路径恢复之间。实现路径恢复的大部分效率，但是具有比路径恢复更局部化并且可能更快和更简单的跨度恢复机制。该概念适用于具有无源波段直通特征的OADM的实现，以支持用于快速光路的逻辑链路旁路跨度。

摘要： Tis invention provides a ‘capacity slice’ nodal switching device (in the ADM-like sense) that is designed for deployment under the p-cycle concept. The device's key architectural properties are access, east and west interfaces, with one spare and working port, on each of these interface sides, plus at least two straddling side interfaces. The straddling side interfaces each have equal line capacity to those of east and west interfaces, but all are usable for working capacity. In application, the plug cards in the nodal switching device are supplied to provide up to two line signal units on the straddling side of the p-cycle device, per diverse span arriving at the site. Network level deployment and configuration of the devices requires that they be arranged in p-cycles.

摘要： A method of modulating a DS3 signal for addition thereto of an auxiliary, transparent signalling channel, the DS3 signal having framing bits which provide a predetermined pattern for which frame-finding circuits hunt to demultiplex the payload of the DS3 signal. The method comprises cyclically forcing an framing-bit error onto every D-spaced framing-bit of the DS3 signal during an initial ON period of an ON-oFF modulation cycle, the ON period and the modulation cycle having lengths such that no more than two verification attempts are required to complete reframing of the signal in the presence of the framing-bit modulation, and wherein the Modulation Spacing, D, is selected so as to provide a low probability of coincidence between the framing-bit Modulation Spacing and a verification window following a secondary reframing hunt.

摘要： A series of nodes in a telecommunications network are connected by a bi-directional transmission path. An outgoing signal passes each of the intermediate nodes in the path and sets a counter timing at each intermediate node. The outgoing signal then returns from the loop node with time information attached to it. As the returning trigger signal passes the intermediate nodes, the intermediate nodes stop counting the elapsed time since the trigger signal passed the intermediate node, and latches the time information. Precision time synchronization information is then determined for each intermediate node by halfing the two way travel time from the intermediate node to the loop node, adjusting for propagation and processing delays, and adding it to the time information from the loop node.

摘要： A characteristic of a signal received via a receive line is monitored and used for automatic control of a line buildout circuit in a transmit signal path. The characteristic is conveniently an amplitude level, or differential amplitude levels for different signal bandwidths, of the received signal. The transmit line buildout circuit includes a transversal filter in which multiplier coefficients or delay times are controlled. The arrangement is particularly useful for digital signal interfaces on a digital cross connect.

摘要： In a broadcast transmission system, in which in normal operation messages and terminal addresses are transmitted between a master station and a plurality of terminals each having an assigned address, the master station initially assigns the addresses to the terminals. In order to isolate each terminal in turn to assign it an address, the master station varies one or more parameters which affect the bit error rate of the terminals while polling the terminals, and each terminal which receives the poll with an acceptable bit error rate responds to the poll. When the master station receives only one response to a poll, it assigns an address to the responding, isolated, terminal which thereafter does not respond to the poll. This procedure is repeated until addresses have been assigned to all of the terminals. The parameter may, in particular, be the strength of the signal transmitted by the master station.

摘要： A communication network in which p-cycles are used to rapidly, simply and efficiently provide for the direct replacement of failed fiber sections with whole replacement fibers. As long as the loss budgets are adequate, entire DWDM wavebands can be restored with no switching or manipulation of individual lightpaths. Following a substitution transient, the DWDM layer would never know the break happened. In environments where fiber switching devices are low cost, and ducts are full of dark fiber, this could provide a very low cost alternative to protect an entire DWDM transport layer (or working capacity envelope) against the single largest cause of outage.
