A method (1000, 1200) for processing management protocol messages within a telecommunication network, comprising: receiving, by a central office computer (132, 142, 300) within a telecommunication node (130, 140) from a network manager computer (110, 120), a message packaged within a first data frame (510, 520, 530), the message conforming to a first protocol and being addressed to a customer premises equipment computer (138, 148, 200, 600) within the telecommunication node, wherein the CO computer communicates with the network manager computer via an access network using the first protocol, and communicates with the CPE computer via a physical data link using a second protocol; determining, by the CO computer, whether or not the CPE computer to which the message is addressed supports the first protocol; when said determining is affirmative (1030, 1050), then encapsulating, by the CO computer, the message conforming to the first protocol within a second data frame (510,520, 530) that conforms to the second protocol; when said determining is not affirmative (1030, 1070), then translating, by the CO computer, the message from the first protocol to the second protocol, and packaging the translated message within a second data frame that conforms to the second protocol; sending, by the CO computer, the second data frame to the CPE computer using the second protocol via the physical data link; further receiving, by the CO computer, a reply within a third data frame (510, 520, 530) from the CPE computer, the message conforming to the second protocol and being addressed to the network manager computer; further determining, by the CO computer, whether or not the CPE computer from which the reply was received, supports the first protocol; when said further determining is affirmative, then decapsulating, by the CO computer, a message conforming to the first protocol within the third data frame, and packaging the decapsulated message within a fourth data frame that conforms to the first protocol; when said further determining is not affirmative, then translating, by the CO computer, the message from the second protocol to the first protocol within a fourth data frame (510, 520, 530) that conforms to the first protocol; and further sending, by the CO computer, the fourth data frame to the network manager computer using the first protocol via the access network. receiving, by a central office computer (132, 142, 300) within a telecommunication node (130, 140) from a network manager computer (110, 120), a message packaged within a first data frame (510, 520, 530), the message conforming to a first protocol and being addressed to a customer premises equipment computer (138, 148, 200, 600) within the telecommunication node, wherein the CO computer communicates with the network manager computer via an access network using the first protocol, and communicates with the CPE computer via a physical data link using a second protocol; determining, by the CO computer, whether or not the CPE computer to which the message is addressed supports the first protocol; when said determining is affirmative (1030, 1050), then encapsulating, by the CO computer, the message conforming to the first protocol within a second data frame (510,520, 530) that conforms to the second protocol; when said determining is not affirmative (1030, 1070), then translating, by the CO computer, the message from the first protocol to the second protocol, and packaging the translated message within a second data frame that conforms to the second protocol; sending, by the CO computer, the second data frame to the CPE computer using the second protocol via the physical data link; further receiving, by the CO computer, a reply within a third data frame (510, 520, 530) from the CPE computer, the message conforming to the second protocol and being addressed to the network manager computer; further determining, by the CO computer, whether or not the CPE computer from which the reply was received, supports the first protocol; when said further determining is affirmative, then decapsulating, by the CO computer, a message conforming to the first protocol within the third data frame, and packaging the decapsulated message within a fourth data frame that conforms to the first protocol; when said further determining is not affirmative, then translating, by the CO computer, the message from the second protocol to the first protocol within a fourth data frame (510, 520, 530) that conforms to the first protocol; and further sending, by the CO computer, the fourth data frame to the network manager computer using the first protocol via the access network.
