|  The AN-miniSDH-A is derived form the card-based AN-miniSDH to provide a more cost effective solution. It is of single board design with fixed number of interface ports. As an ADM MUX, it has two STM-1 fiber optic ports, and a set of service ports. According to the number of service ports, the AN-miniSDH-A comes in different models, as shown in below table. Model | STM-1 optical Ports | E1 Ports | Ethernet Ports | V.35 Ports | AN-miniSDH-A/841 | 2 | 8 | 4 | 1 | AN-miniSDH-A/840 | 2 | 8 | 4 | 0 | AN-miniSDH-A/441 | 2 | 4 | 4 | 1 | AN-miniSDH-A/440 | 2 | 4 | 4 | 0 | AN-miniSDH-A/400 | 2 | 4 | 0 | 0 |
